Question

hEY YOU! STOP SCROLLING! STOP IT! TAKE A FEW MINUTES TO HELP ME OUT HERE?? Find an equation of the line containing the given pair of points. Express your answer in the form x=​a, y=B, or y=mx+b ​(0 ​,0​) and ​(3 ​,7​)

Answer 1

To find the slope (m) of the equation, you use the slope formula:

`m = (y_(2)-y_(1))/(x_(2)-x_(1))`

Now you plug in the points into the formula

`m = (7 - 0)/(3 - 0) = (7)/(3)`

`y = (7)/(3) x + b`

Now you need to find b, to do so you plug in either of the points into the equation.

`0 = (7)/(3) (0) + b`

0 = b

The equation of the line is:

`y = (7)/(3)x`
