General equation of slope intercept form is y=mx+c. m=-5, b= - 7 = c. Plugging these values in general equation you'll get, y= - 5x - 7. Option C is the correct answer.
Answer:
direct variation

Step-by-step explanation:
Answer:
f(-3)=9
Step-by-step explanation:
We want to find what f(x), or y is, when x is equal to -3.
f(x)=x^2
We want to find f(-3). Therefore, we can substitute -3 in for x.
f(-3)=(-3)^2
Evaluate the exponent. -3^2 is the same as -3*-3.
f(-3)=-3*-3
f(-3)=9
