Answer:

x=3

Step-by-step explanation:

so...

13=x²+4.

start by subtracting 4 from each side to get the numbers on one side.

13-4=, and 4-4=0

now, we just have 9=x².

to undo a square, one must square root. so,

\sqrt{9}  = 3

and

\sqrt{x {}^{2} }  = x

now, x=3.

The slope intercept form of (-4, 8) and (9, 8)
Black_prince [1.1K]

Step 1: Find the slope

(y-y)/(x-x) = (8-8)/(9+4) = 0

Step 2: Substitute into the slope intercept equation

y - y = m(x - x)

y - 8 = 0(x - 9)

If the problem just wants plain, slope intercept form, then this is your answer.

If not, y = 8
