If a line is perpendicular to other his slopes are the opposite inverse of each other
So, if y = -2x - 4 we have the slope of -2, so the slope of the other line will be the opposite inverse which means
opposite of -2 = 2
inverse of 2 = 1/2
So our slope is 1/2
(y - yo) = m.(x - xo)
(y - 4) = 1/2.(x - 3)
y - 4 = x/2 - 3/2
y = x/2 - 3/2 + 4
y = x/2 + 5/2
Answer:
C
Step-by-step explanation:
A proportional graph is a line. Every line has a slope. The slope is found by subtracting two points as a ratio. The line has points (0,0) and (2,6).
6-0 = 6
2 -0 = 2
The ratio is vertical over horizontal so 6/2 = 3.
The equation is y = 3x.

Answer:
m∡1 + m∡2 = 180
Step-by-step explanation:
m∡1 + m∡2 = 180
This is because supplementary means they add up to 180°.
