Question

Find the y - intercept of the line formed by: −1x+4y=23

Answer 1

Solve for y on the expression:

`-1x+4y=23`

Add both sides by 1x:

`-1x+1x+4y\text{ =23+1x}`
`4y=\text{ 23+1x}`

Divide both sides by 4:

`(4y)/(4)=(23+1x)/(4)`
`y\text{ =}(23)/(4)+(x)/(4)`

Where 1/4 is the slope and 23/4 represents the y-intercept.

The ordered pair for the y-intercept is (0.23/4).
