Question

Which statement is true about the two lines whose equations are given below?

y =
= 3x + 2
y = -4x + 9
A.
The lines are parallel.
B.
The lines are perpendicular.
The lines intersect but are not perpendicular.
C.
D.
The lines coincide.

Answer 1

C. The lines intersect but are not perpendicular.

Explanation:

The slopes (x-coefficients) of these lines are 3 and -4. They are different, but their product is not -1. Lines with different slopes are distinct lines that will intersect. If the product of their slopes is -1, they are perpendicular.

The lines intersect but are not perpendicular.
