Explanation:
You want to calculate the slope of this function:
3.5-6/0-(-2)
-2.5/2
=-1.25
=-5/4
So now, you start plugging in the point slope stuff:
point-slope form of equation: y-y1 = m(x-x1)
For (-2, 6):
y-6 = -5/4(x+2)
For (0, 3.5)
y-3.5 = -1.25x
For (2,1)
y-1 = -5/4(x-2)
For (4,-1.5)
y+1.5 = -5/4(x-4)
So the answers are:
1, 4, 5
