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?

Answer 1

you need to get the slope-int form first
\(y = mx + b\)
you already have the slope \(m = 2\) and the x and y values (0, -1). find \(b\)

\(\color{red}{-1 = 2(0) + b}\)
solve for b and then u should get the slope-int form.

Answer 2

-1?

Answer 3

correct :)

Answer 4

so we now have:
\(y = 2x -1\)

Answer 5

is it (2,1) ?

Answer 6

plug in the x and y value...
\(1 = 2(2) - 1\)
\(1 = 4 - 1\)
\(1 \neq 3\)

Answer 7

(2,1) does not fit in the line

Answer 8

okay

Answer 9

is it (1,1)?

Answer 10

\(1 = 2(1) - 1\)
\(1 = 2 - 1\)
\(1 = 1\) <-- that's correct :)

Answer 11

ok thank you so much :)
