Find the Slope: (0,0)  (1, -9)

m = -9

100
Put into slope intercept: 1y + 2x = 4
y = 4 - 2x
100

f (x) = x2 + x, when x = -1

f(-1) = 0

100
Write in point slope: m = 6 (3, -4)
y + 4 = 6 (x - 3)
100
Find x and y intercepts: x + y = 2
x = 2, y = 2
200

Find the slope: (3, -6) (-1, -2)

m = -1

200
Put into slope intercept: m = 5 and y-intercept = 6
