Question

If a line contains the point (0, -1) and has a slope of 2, then which of the following points also lies on the line?

(2, 1)
(1, 1)
(0, 1)

Answer 1

the slope two means it goes up 2 and to the right 1. so 2,1

Answer 2

(y-y1) =m(x-x1)
(x1,y1) are given and so is m
put value find the equation of line
then check which of the given point does satisfies the given line

Answer 3
