Write an equation in slope-intercept form of the line through point P(–10, 1) with slope –5.?

Question

a. y = –5x – 49

b. y – 1 = –5(x + 10)

c. y – 10 = –5(x + 1)

d. y = –5x + 1

Answer 1

y - 1 = (- 5) (x + 10)
y = - 5x - 50 + 1
y = - 5x - 49
OPTION b

Answer 2

Slope intercept means y = mx + b

But we also know that an equation in point-slope form with a slope m and a point (p,q) is

y-q = m(x-p)

y-1 = -5(x+10)

y = -5x - 50 + 1

y = -5x - 49

The answer is a)
