Function Rule:
x| -10| -4| 2+|8 |14
y| 80 |62| 44| 26| 8
If x=0, what is y?
first find equation of the line:
a slope is: m=%2862-80%29%2F%28-4-%28-10%29%29=-18%2F6=-3
y-y%5B1%5D=m%28x-x%5B1%5D%29
y-80=-3%28x-%28-10%29%29
y=-3%28x%2B10%29%2B80
y=-3x-30%2B80
y=-3x%2B50
If x=0, then y=-3%2A0%2B50=>y=50
