Question

What is the equation of the line through the origin and (7,2)

Answer 1

y=2/7x

Explanation:

Answer 2

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

Explanation:

First: find slope of line by using the formula
`(y_2-y_1)/(x_2-x_1)` with the two points (0,0) and (7,2)

slope(m) =
`(y_2-y_1)/(x_2-x_1)` =
`(2-0)/(7-0)` =
`(2)/(7)`

Second: plug your data into the point slope formula
`y-y_1=m(x-x_1)`

y-0=
`(2)/(7)`(x-0)

y-0=
`(2)/(7)`x

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