Answer:
The perpendicular line would be y = -2x - 4
Step-by-step explanation:
First we must solve the original equation for y.
x - 2y = 7
-2y = -x + 7
y = 1/2x - 7/2
In order to find the equation of this line, we first have to note that perpendicular lines have opposite and reciprocal slopes. Therefore, since the original line has a slope of 1/2, we know the new line will have a slope of -2. Now we can use that information along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -2(x + 3)
y - 2 = -2x - 6
y = -2x - 4
Answer:
x = -21
Step-by-step explanation:
62 + 2x - 20 = 0.
Combine like terms
42 +2x =0
Subtract 42 from each side
42-42 +2x = 0-42
2x = -42
Divide each side by 2
2x/2 = -42/2
x = -21
