Question

Choose which lines are perpendicular. after doing the necessary work, circle your final answer.

line p passes (4,0) and (6,4)
line w passes through (0,4) and (6,4)
line r passes through (0,4) and (0,0)

a) line p and line q
b) line p and line r
c) line q and line r
d) none of these

Answer 1

First, we determine the slope of the line given, y = 2x + 5
The equation is in slope-intercept where in the slope of the line is the numerical coefficient of x. The slope is therefore 2.
The equation of the new line becomes,
y - 6 = 2(x - 4)
Simplifying, y = 2x - 2
