Question

Find the y-intercept of the graph of 2x-5y=10

Answer 1

y-intercept: ( 0 , − 2 )

Explanation:

To find the y-intercept, substitute in 0 for x and solve for y

Answer 2

(0,-2)

Explanation:

Start with:

`2x-5y=10`

We are going to want this equation in slope-intercept form.

`y=mx+b`

`mx=slope`

`b=y-intercept`

To get the equation in slope intercept from, start by subtracting
`2x` from both sides of the equation:

`-5y=-2x+10`

Now, divide both sides of the equation by
`-5`:

`y=-(2)/(5)x -2`

`b=-2`

`(0,-2)`
