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)

Answer 1

y-1 = 2x +16

1) Gathering the data

m=2

(-8,1)

2) The equation of the line in point-slope form is obtained through a formula:

(y-y_1)=m(x-x_1)

3)Plugging into the formula the parameters.

(y-1) =2[x-(-8)]

(y-1)=2(x+8)

y-1 = 2x +16
