Answer:
Step-by-step explanation:
As per the same approach I answered in a similar problem:
The slope is the Rise/Run between the two points. The change in y for every change in x. Take the two points and calculate theRise/Run:
RISE = (-11 - 9) = -20
RUN = (3 - (-2)) = 5
Rise/Run, or slope, is = -20/5 or -4
I graphed this line and the two points (attached).
Answer:
c= -20
x= 38
Explanation:
Solve for x and c by simplifying both sides of the equation, then isolating the variable.
hope this helps!

Answer: perpendicular slope is -2/3</h3>
=================================================
Work Shown:
Solve the given equation for y
2y = 3x - 10
y = (3x-10)/2 ..... divide both sides by 2
y = (3x)/2 - 10/2
y = (3/2)x - 5
The equation is in y = mx+b form with m = 3/2 as the slope.
The perpendicular slope is -2/3 because we flip the fraction and the sign from positive to negative.
Note how multiplying the original slope 3/2 and the perpendicular slope -2/3 leads to -1
(3/2)*(-2/3) = -1
This is true for any pair of perpendicular lines, assuming neither line is vertical.
