Answer: 5=x

Step-by-step explanation:

Ok, so if F(x)=15, then the equation would look like this: $15=5x-10$

The next step would be to add the 10 over from the right to the left side to get $25=5x$

Now divide both sides by 5 to get the answer.

What is the slope of the line through (-9,-6) and (3,-9)?

tatuchka [14]

Answer:

slope = - $\frac{1}{4}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 9, - 6) and (x₂, y₂ ) = (3, - 9)

m = $\frac{-9+6}{3+9}$ = $\frac{-3}{12}$ = - $\frac{1}{4}$
