How to graph y=-3x+15
steposvetlana [31]

Answer:

Well first you put the y-intercept on the graph. In this case it would be 15

So graph the point (0,15)

The you do the slope which is 3

so you always do rise over run for slope.

If 3 were a fraction it would be 3/1 so go up 3 points and the go right 1 point from (0,15)

hope this helps .-.

Find f(-2).<br> A. 4<br> B. 8<br> C. 10<br> D. 20
il63 [147K]

Answer:

D. 20

Step-by-step explanation:

First, we need to plug in -2 to all the spots where x are. The new equation we have then is f(-2)= 2(-2)^2 - 3(-2) + 6. Then, we plug in the exponent to get 2(4) - 3(-2) + 6. We can then multiply to get 8 + 6 (since the three was negative as well) + 6, which equals 20.
