Answer:
y=x-3
Explanation:
slope intercept form equation is y=mx+b
b is the y intercept(where it crosses on the y-axis)
b=-3
m is the slope
slope is rise over run (start from -3)
slope is 3 over 3 (count up 3 from -3, count right 3)
3 over 3 is 1
1x is the same as x
final answer y=x-3
hope this helped
