Question

How do I find point-slope and slope-intercept form from a graph?

Answer 1

find the y - intercept and the slope
y - int. - where the line intersects the y - axis
slope you can find by using rise over run

Answer 2

The slope is 1 over 1 and the y intercept is -3

Answer 3

Can you walk me through it?

Answer 4

You could take any point of the line for that matter and taking the x value of that point and the y value of that point and putting them into the point slope formula

Answer 5

ok... I still don't get it.

Answer 6

Sure...find a point on the line first

Answer 7

(-4,-1)

Answer 8

and you said the slope was 1 over 1 so the slope equals 1

Answer 9

Ok

Answer 10

This is the formula...
