Answer:
1) y = -1/2x - 1
2) y = -1
3) y = -2/4
4) y = 5/2 - 3
Step-by-step explanation:
1)
use rise (up or down) over run (left or right)
the rise is -1
the run is 2
therefore, the slope is -1/2
the y intercept is -1 (y intercept is when it touches the Y line)
y = -1/2x - 1
2)
y = -1
3)
y = -2/4
4)
y = 5/2 - 3
