Question

Find the equation of a graph that slopes downward and has a y-intercept of -5.

y = 4x + 5

y = 4x - 5

y = - 4x + 5

y = - 4x - 5

Question

{(-2, 5), (2, 9), (6, -2), (8, 4), (12, 6)}

No

Yes

Question

Evaluate the function for the given value of x.

f(x) = -3x - 9 when x = 5

f(5) = - 20

f(5) = - 24

f(5) = - 26

f(5) = 24
