Question

Write a linear function f with f(0)=7 and f(3)=1

Answer 1

F(0)=7(0)
=0

f(3)=1(3)
=3

Answer 2

F(x)=-2x+7. Slope is delta y over delta x. So the change is y is -6 and the change in x is 3. -6 over 3 simplifies to -2. That is the slope. The y-intercept is where it intersects the y-axis, or when the x value is equal to zero. In this case, the y-intercept is 7.
