<h2>
Answer:</h2>
First we must find the opposite-reciprocal of the original slope.
current slope: 
new slope: 
Using the new slope and the given point, we will plug them into slope-intercept form and solve for b, the y-intercept.

The y-intercept is
.
Now, we can write the formula for the new line.
Slope-intercept form: 
Point-slope form: 
Answer: D
<u>Step-by-step explanation:</u>
Let x represent the score on her next test


78 + 92 + 88 + 89 + x = 5(90)
347 + x = 450
<u> -347 </u> <u>-347 </u>
x = 103
G(-4) = 4^2 + 3(-4) - 2
16 - 12 - 2
4 - 2
answer: 2
