Example Question #21 : Slope
What is the slope of the graph?
0
Slope is .
We can pick any two points on the graph and count the rise and run. This graph goes through (0,0), so lets pick that point. It also looks like (2,3) is on the graph.
So, from (0,0) to (2,3), you go up 3, and over 2.
This makes our slope
Example Question #22 : Slope
Find the slope of the line connecting the points and .
Find the slope of the line connecting the points and .
To find our slope, we need to recall "Rise over Run." This can also be thought of as change in y over change in x.
Now, all we need to do is plug in our points and solve. It doesn't matter which pairs are x and which are y, but we must keep it consistent.
Now let's simplify:
So, we get which cannot be reduced, so we are all set!
Example Question #22 : Slope
What is the slope of the line perpendicular to the line running between the points and ?
Recall that slope is calculated as:
This could be represented, using your two points, as:
Based on your data, this would be:
Remember, the question asks for the slope that is perpendicular to this slope! Don't forget this point! The perpendicular slope is opposite and reciprocal.
Therefore, it is:
Example Question #1 : X Intercept And Y Intercept
Which of the following equations has as its graph a line with -intercept 9?
The equation in which when is graphed by a line that includes point - that is, its -intercept is 9. Therefore, substitute 0 for in each equation and solve for .
The correct choice is , since is a solution of this equation.
Example Question #2 : X Intercept And Y Intercept
Which of the following equations has as its graph a line with -intercept ?
The equation in which when is graphed by a line that includes point - that is, its -intercept is . Therefore, substitute 0 for in each equation and solve for .
The correct choice is , since is a solution of this equation.
