Question

What is the x-intercept of the equation below? 5x - 8y = 10 A. ( 2 , 0 ) B. ( 0 , 2 ) C. ( 0 , -5/4 ) D. ( -5/4 , 0 )

Answer 1

A. ( 2 , 0 )

Explanation:

`5x - 8y = 1`

Let y = 0

`5x-8(0) =10`

Multiply ; 8×0=0

`5x-0=10`

Collect like terms and simplify

`5x =10+0\\\\5x =10`

Divide both sides of the equation by 5

`(5x)/(5)= (10)/(5)`

Simplify

`x =2\\\\(2,0)`
