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:
7
Step-by-step explanation:
7q^2 - 28 = 0
7q^2 = 28
q^2 = 4
q = +/-2
solution set is {-2,2}
