Question

A line has a slope of 2 and contains the points (1, 3) and (2, y). The value of y is

-1
1
5

Answer 1

Do you know the slope formula?

Answer 2

y=mx+b

Answer 3

No, that is the slope-intercept formula.

The slope formula is.
\(\Huge\sf\frac{y_2-y_1}{x_2-x_1}\)

Answer 4

Yes

Answer 5

And the points are \(\large\sf (x_1,y_1), (x_2,y_2)\)

Answer 6

Yes

Answer 7

And they gave us
\(\large\sf (1,3), (2,y)\)

So plug it in to the formula.
