Plug 7 into each y. 9(7) -4(7) +3
63-28+3
The answer is 38
T because all variables are letters
If QR is a median, then:

We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:

<h3>Answer: A. 6</h3>
Answer:
y-intercept = 4
x-intercept = 2
Step-by-step explanation:
you can divide the equation through by 4 and change into the y=mx+c form to find c, the y intercept so the y-intercept = 4.
for the x intercept make the y=0 (because the coordinate point where the line crosses the x axis must have y=0) and then you get 8x=16 so x=2
