But equation in y intercept form.. what ever is in front of the x will be the slope for that equations line
5x=y-12
5x+12=y or y=5x+12
Slope is 5
If any line is parallel to this one it must have slope of 5
Answer:
![y = \frac{-5}{3}x+200](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-5%7D%7B3%7Dx%2B200)
Step-by-step explanation:
Find the value of the slope.
Find the value of the y-int.
<em>good luck, i hope this helps :)</em>
Play A: y=15x+76
Play B: y=-x^2 +36x-4
set them equal:
15x+76=-x^2 +36x-4
80=-x^2+21x
x^2-21x+80=0
-> solve for x
for example with the quadratic equation formula or solving the square
factorized:
(x-16)(x-5)=0
so x1=5 and x2=16
insert them into y=15x+76
y1=151, y2=316
so (5,151) and (16,316) are days with equal attendance for both plays which is option C
