Answer:

y = 1/2x + b

Explanation:

The equation of a line is mx + b

m is the slope and b is the y-intercept

To find the equation of a line, you need to know the slope and y-intercept.

To find the y-intercept, go to the y-axis(up and down) and look for where the line meets the line. (-3)

To find the slope:

Find two points of the line that follow the grid.

Example: (4, -1) and (2, -2)

Then do y1 - y2/x1 - x2 to get -1--2/4-2 to get 1/2.

Look back to the equation y = mx+b and replace m with 1/2 and b with -3

You get y = 1/2 +-3 or y = 1/2x-3

So the equation of the line is y=1/2x -3
