Question

A line passes through the points (6, 8) and (5,5). What is its equation in slope-intercept

form?

Answer 1

y = 3x -10

Explanation:

Use the method
`(rise)/(run)`.

I took a screenshot of the graph below, as an example of the rise over run method.

3 ÷ 1 = 3

To find the y intercept, count down on the graph until you reach the point where the line crosses.

In this case, the line crossed at -10 on the y-axis.

(Look at the second image)

So plug the numbers into the equation, and then you get y = 3x -10.
