Is (3,-9) a solution to f(x) = -3x?

Yes, the point (3,-9) is a solution to f(x) = -3x

Explanation:

Since y = f(x), we can say that f(x) = -3x is the same as y = -3x

The point (3,-9) means x = 3 and y = -9 pair up together

Lets plug these values into the equation

y = -3x

y = -3(3) replace x with 3

-9 = -3(3) replace y with -9

-9 = -9

We get the same thing on both sides, so the point (x,y) = (3,-9) is a solution to y = -3x. Consequently, it's also a solution to f(x) = -3x.

Step-by-step explanation:

f(x)= -3x

-3(3)= -9

yes, (3, -9) is the solution

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
