For this case, we must find the inverse of the following function:
To find the inverse we follow the steps below:
We rewrite the denominator:
We exchange variables:
We solve for y:
We multiply on both sides of the equation by (y-7)
We subtract xy on both sides of the equation:
We add 1 to both sides:
We factor for y:
We divide both sides by (-5-x):
So, we have:
Answer:
You already know the slope is 3 and you have the point, so you would plug it into y = mx + b
-2 = y
3 = m
-5 = x
Plug in:
-2 = 3(-5) + b
Solve:
-2 = -15 + b
-2 (+15) = -15 + b (+15)
13 = b
Now you have b, so you can form the equation where the slope is 3x and the y-intercept is 13.
Final answer: y = 3x + 13
Answer:
-2 + × = y
Step-by-step explanation:
I think this is the answer because it's asking for an expression which this would be one.
