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

Answer: B. (1,1)

Explanation:

Slope-intercept form: →
`y=mx+b`

m: represents the slope and is constant.

b: represents the y-intercept.

Used rise/run:

`(rise)/(run)`

`m=(rise)/(run)`

The y-intercept is the point on a graph at which the graph crosses the y-axis.

Hope this helps!

Thanks!

Answer 2

the answer is B. because if you make an equation in the form y=mx+b then you can solve the equation by inputting x where x goes in the equation and solving. BTW the equation would be y=2x-1
