looking at the graph, the y intercept (or where it crosses the y axis) is -2
the slope = change in y/ change in x
from one point to the next, we go up one, to the right one
(up and right are positive, down and left are negative)
= +1/+1
m =1
slope intercept form of a line
y = mx+b
m is the slope, b is the y intercept
y = 1x -2
y = x-2
Answer: y = x-2
