Question

17) What is the slope of a line perpendicular to the line y = 2x - 3?

OA) -2.
OB) 1/2
OC) -1/2
OD 2

Answer 1

C.) -1/2

Explanation:

Perpendicular lines have opposite reciprocal slopes.

• Opposite = opposite signs (+ & -)

• Reciprocal = flipped positions in fractions (1/2 ⇒ 2/1)

Therefore, the slope of a line perpendicular to the line y = 2x - 3 must be -1/2.
