Question

Identify an equation in point-slope form from the line perpendicular to y=-4x-1 that passes through (-2,7)

Answer 1

y-7= 1/4 (x+2)

Explanation:

perpendicular lines have a slope that are negative reciprocals

so y = -4x-1 has a slope of -4

the negative reciprocal is - (-1/4) = 1/4

point slope form

y-y1 = m(x-x1)

y-7 =1/4(x--2)

y-7= 1/4 (x+2)
