Answer:
(-7, -10)

Step-by-step explanation:

Substitute x for -7.

Multiply 4 by -7.

Add 28 on both sides.

Divide -4 on both sides.

Answer:
24
Step-by-step explanation:
f(x)=x^2+2x
Let x= 4
f(4)=4^2+2*4
= 16 + 8
= 24

Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.
So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.
For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.
