The air Temperature is -12C at sunrise and rises 4 degrees c every hour for several hours the air temperature after x hours is represented by the function f(x)=4x-12

Let f(x) = y.

y = 4x - 12

Let x = 0

y = 4(0) - 12

y = - 12

This leads to the point (0, -12).

Let y = 0.

0 = 4x - 12

1 2 = 4x

12/4 = x

3 = x

This leads to the point (3, 0).

We now graph both points and then connect each point with a straight line.
