Question

A line passes through the point (-5, -7) and has a slope of 2.

Write an equation in slope-intercept form for this line.

Answer 1

Answer: y =2x+3

Explanation:

y=mx+b

y=-7 x=-5

-7=2(-5)+b

-7=-10+b

b=3

y=2x+3

Answer 2

y =2x +3

Explanation:

 m=2, a point (-5, -7)

y - -7 = 2(x - -5)

y + 7 = 2x + 10

y =2x +3
