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?
A. (2, 1)
B. (1, 1)
C. (0, 1)

Answer 1

use the point slope formula first

Answer 2

use the point-slope form

Answer 3

y-y1=m(x-x1)

Answer 4

\[y-y_1=m(x-x_1)\]
where m is your slope
x1 and y1 are your point coordinate

Answer 5

then solve for y

Answer 6

y-(-1)=2(x-(0))

Answer 7

y=2x-1

Answer 8

then do the same with the rest and whichever looks like your answer would be the answer in the choice

Answer 9

graph that equation and then see which point is on that line
