Question

Find the equation of the line which is parallel to y = 4x + 3 and goes through the point (4, 5)​

Answer 1

• y = 4x - 11

Explanation:

The given line has a slope m = 4.

We know parallel lines have equal slopes.

Use point - slope equation and substitute the coordinates of the given point to get:

• y - 5 = 4(x - 4)
• y - 5 = 4x - 16
• y = 4x - 16 + 5
• y = 4x - 11
