What are slope and y intercept for the following: y = -1/6x - 2
slope = -1/6 y intercept = 2
slope = -6 y intercept = -2
slope = -1/6 y intercept = -2
slope = -2 y intercept = -1/6

Solve. -3(x + 2) = 6
x = 4
x = 4/3
x = -4/3
x = -4

Write the exponential function equation for points (-1, -1) and (0, 3). Remember f(x)=a(b
x
)
f(x)=3(1/3)x
f(x)=-3(3x)
f(x)=-1(-3x)
f(x)=3(-3x)
