How do you solve parallel and perpendicular lines?
For a parallel line the slopes are the same but if it’s perpendicular the slope is going to change from five over one to one over five with a negative sign. So you need to flip the fraction.
What would make a scatter plot and its corresponding line of fit more useful to make accurate predictions?
SOLUTION: The more data you have, the more accurate the scatter plot and line of fit will be.
How do you determine whether a scatter plot has a positive or negative correlation?
A scatter plot can show a positive relationship, a negative relationship, or no relationship. If the points on the scatter plot seem to form a line that slants up from left to right, there is a positive relationship or positive correlation between the variables.
How do you find perpendicular lines?
If two non-vertical lines in the same plane intersect at a right angle then they are said to be perpendicular. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the coordinate plane. The slopes of two perpendicular lines are negative reciprocals.
How do you write a parallel equation?
Writing Equations of Parallel Lines Tutorial – YouTube
What is the equation of parallel lines?
Two lines are parallel lines if they do not intersect. The slopes of the lines are the same. f(x)=m1x+b1 and g(x)=m2x+b2 are parallel if m1=m2 f ( x ) = m 1 x + b 1 and g ( x ) = m 2 x + b 2 are parallel if m 1 = m 2 .
What are the 3 types of scatter plots?
What are the Three Types of Scatter Plot?
- Positive Correlation.
- Negative Correlation.
- No Correlation (None)
How do you explain a scatter plot?
Scatter plots are the graphs that present the relationship between two variables in a data-set. It represents data points on a two-dimensional plane or on a Cartesian system. The independent variable or attribute is plotted on the X-axis, while the dependent variable is plotted on the Y-axis.
How do you explain a scatter diagram?
The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the tighter the points will hug the line.
What is perpendicular lines example?
Perpendicular lines are lines that intersect at a 90-degree angle. So, for example, line ST is perpendicular to line CD. So line ST is perpendicular to line CD.
What is the equation of a parallel line?
In two dimensions, parallel lines have the same slope . We can write the equation of a line parallel to a given line if we know a point on the line and an equation of the given line. y=2x+3 . Parallel lines have the same slope.
What is example of parallel lines?
The real-life examples of parallel lines include railroad tracks, the edges of sidewalks, rails of a ladder, never-ending rail tracks, opposite sides of a ruler, opposite edges of a pen, eraser, etc.
How do you write parallel equations?
How do you draw a scatter graph?
For each pair of data, put a dot or a symbol where the x-axis value intersects the y-axis value.
…
Scatter Diagram Procedure
- Count X/2 points from top to bottom and draw a horizontal line.
- Count X/2 points from left to right and draw a vertical line.
- If number of points is odd, draw the line through the middle point.
What is an example of a scatter plot?
A Scatter (XY) Plot has points that show the relationship between two sets of data. In this example, each dot shows one person’s weight versus their height.
Ice Cream Sales vs Temperature.
| Temperature °C | Ice Cream Sales |
|---|---|
| 11.9° | $185 |
| 15.2° | $332 |
| 18.5° | $406 |
| 22.1° | $522 |

What are parallel lines examples?
Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions. For example, the opposite sides of a rectangle represent parallel lines.
What are 2 perpendicular lines?
Two distinct lines intersecting each other at 90°, or a right angle, are called perpendicular lines. Here, AB is perpendicular to XY because AB and XY intersect each other at 90°. The two lines are parallel and do not intersect each other. They can never be perpendicular to each other.
Are two equations parallel?
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.

What is scatter diagram with example?
Scatter Plots. A Scatter (XY) Plot has points that show the relationship between two sets of data. In this example, each dot shows one person’s weight versus their height. (The data is plotted on the graph as “Cartesian (x,y) Coordinates”)
