Question

Write the equation of a line in point slope form that passes through (-1, 4), and is perpendicular to y = -4x +3

Answer 1

y = 1/4x + 17/4

Explanation:

Slope-Intercept Form: y = mx + b

Perpendicular lines have the negative reciprocal slope.

m = 1/4

y = 1/4x + b

4 = 1/4(-1) + b

4 = -1/4 + b

17/4 = b

y = 1/4x + 17/4
