Question

What equation of the following line? Be sure to scroll down first to see all answer options. (1,7) (0,0)

Answer 1

Between the two points, the x value goes down 1 and the y goes down 7. A very steep downward slope of -7. The equation of the line is y=-7x

Answer 2

`y=7x`

Explanation:

We have been given a graph. We are asked to find the equation of the line.

First of all, we will find slope of line using points (1,7) and (0,0).

`m=(y_2-y_1)/(x_2-x_1)`

`m=(7-0)/(1-0)`

`m=(7)/(1)`

`m=7`

We can see that y-intercept is 0.

We will write he equation in slope-intercept form
`y=mx+b`, where b represents y-intercept and m represents slope.

`y=7x+0`

`y=7x`

Therefore, our required equation is
`y=7x`.
