Write the slope-intercept form of the equation for the line.

A.)y=3x-1
B.)y=1/3x+1
C.)y=1/3x-1
D.)y=-3x-1

A.) y=3x-1

Step-by-step explanation:

Point-slope form can be shown using the equation: y = mx+b

In this case, m is slope, and b is the y-intercept.

Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.

The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.

If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.
