Find the slope first by using rise/run
![m=\frac{6-(-1)}{4-(-2)}\\m=\frac{6+1}{4+2}\\m=\frac{7}{6}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6-%28-1%29%7D%7B4-%28-2%29%7D%5C%5Cm%3D%5Cfrac%7B6%2B1%7D%7B4%2B2%7D%5C%5Cm%3D%5Cfrac%7B7%7D%7B6%7D)
![y=mx+b\\y=\frac{7}{6}x+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb%5C%5Cy%3D%5Cfrac%7B7%7D%7B6%7Dx%2Bb)
We need to find the y-intercept. Substituting one of given ordered pairs. I will use (-2,-1).
Substitute x = -2 and y = -1 in the equation.
![-1=\frac{7}{6}(-2)+b\\-1=\frac{7}{-3}+b\\-1=-\frac{7}{3}+b\\-1+\frac{7}{3}=b\\b=\frac{4}{3}](https://tex.z-dn.net/?f=-1%3D%5Cfrac%7B7%7D%7B6%7D%28-2%29%2Bb%5C%5C-1%3D%5Cfrac%7B7%7D%7B-3%7D%2Bb%5C%5C-1%3D-%5Cfrac%7B7%7D%7B3%7D%2Bb%5C%5C-1%2B%5Cfrac%7B7%7D%7B3%7D%3Db%5C%5Cb%3D%5Cfrac%7B4%7D%7B3%7D)
Thus the y-intercept is 4/3.
From y = mx+b, the equation is.
![y=\frac{7}{6}x+\frac{4}{3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B7%7D%7B6%7Dx%2B%5Cfrac%7B4%7D%7B3%7D)
Answer:
It's choice B.
Step-by-step explanation:
Let's look the one you have chosen (A):
f(x) = x - 2/ 7 + 8
x-2 / 7 = f(x) - 8
x- 2 = 7(f(x) - 8)
x = 7(f(x) - 8) + 2
The inverse)= 7(x - 8) + 2
So it's not A.
B. f(x) = 5(x/4) - 3
5x / 4 = f(x) + 3
5x = 4(f(x) + 3)
x = 4(f(x) + 3 / 5
So the inverse is 4(x + 3) / 5
So it is B.
Yes that’s correct
14 x 2 =28
28 - 5
=23
C>12
Y=-3 -3+13= 10
