Question

Given: y = 3x - 4.

What is the x-intercept?

Answer 1

x- intercept =
`(4)/(3)`

Explanation:

to find the x-intercept, that is where the line crosses the x-axis.

let y = 0 in the equation and solve for x, that is

3x - 4 = 0 ( add 4 to both sides )

3x = 4 ( divide both sides by 3 )

x =
`(4)/(3)` or (
`(4)/(3)`, 0 )

Answer 2

x-intercept is 4/3.

Explanation:

We have been given the linear equation
`y=3x-4`

For x-intercept, y = 0

Hence, plugging y=0 in the equation and solve for x

`3x-4=0`

Add 4 to both sides

`3x=4`

Divide both sides by 3

`x=(4)/(3)`

Hence, x-intercept is 4/3.
