Question

Find the equation of a line that passes through the points (-1,-3) and (1,-5). Leave your answer in the form y = m x + c

Answer 1

y = 1x -4

Explanation:

In the 2 images I put here, you can see the line, y intercept, and slope.

Let's solve for m (slope):

`m=(rise)/(run)=(2)/(2)=1`

2/2 is the rise over run.

To get rise over run, you have to count how many squares you need to get to a certain longitude from point A to point B, and then, count the squares to get to the certain latitude. In this case, the longitude is 2, and the latitude is 2. Remember, a graph is just like coordinates.

Therefore, the slope, m is equal to 1.
