Answer: y= 3x+8

Step-by-step explanation:

y= mx +b

y= 3x + b

Then, you substitute to solve for b: -5 as x and -7 as y

-7= 3(-5) +b

-7= -15 +b

8= b

So your answer is y= 3x +8

Solve y = x^2 +11 for x.

lisabon 2012 [21]

Answer:

x = ± $\sqrt{y-11}$

Step-by-step explanation:

Given

y = x² + 11 ( subtract 11 from both sides )

y - 11 = x² ( take the square root of both sides )

± $\sqrt{y-11}$ = $\sqrt{x^2}$ , hence

x = ± $\sqrt{y-11}$
