Question

The equation for line w is y = 2x – 3. Line d contains the point (4, -1) and is parallel to line w. Which equation
describes line d?

Answer 1

Answer:

y = 2x - 7

Step-by-step explanation:

y = 2x - 3

Gradient of line w = 2

Gradient of line d = 2

i.e line w and d are parallel.

Equation of line d is:

y - (-1) = 2(x - 4)

y + 1 = 2x - 8

y = 2x - 7
