Question

21. Line p passes through Point (-4,1) and has a slope of 5 What is the equation of Line p in standard form?

A)2x - 5y = 22
B)2x - 5y = - 13
C)5x - 2y = 13
D) 5x - 2y = -22

Answer 1

Explanation:

Point( -4 , 1) ; slope = m = 5

Point-slope form:

y - y1 = m(x -x1)

y - 1 = 5(x - [-4])

y - 1 = 5(x + 4)

y - 1 = 5x + 5*4

y - 1 = 5x + 20

y = 5x + 20 + 1

y= 5x + 21
