Question

Which equation is the equation of the line, in point-slope form, that has a slope of 2 and passes through the point (−8, 1) ? Responses y−8=2(x+1) y minus 8 equals 2 open parentheses x plus 1 close parentheses y−1=2(x+8) y minus 1 equals 2 open parentheses x plus 8 close parentheses y−1=2(x−8) y minus 1 equals 2 open parentheses x minus 8 close parentheses y−8=−2(x−1)

Answer 1

y - 1 = 2(x + 8)

Explanation:

the equation of a line in point- slope form is

y - b = m(x - a )

m is the slope and (a, b ) a point on the line

given slope m = 2 and (a, b ) = (- 8, 1 ) , then

y - 1 = 2(x - (- 8) ) , that is

y - 1 = 2(x + 8)
