Question

What are the coordinates of the x-intercept of the graph of the equation y-2x=8?

Answer 1

`(-4, 0)`

Explanation:

x-intercept is where the graph of the equation crosses the x-axis. All points on the x-axis have a y-coordinate = 0.
Substitute y = 0 into equation.
`0-2x=8` ; solving `x=-4`
Coordinates of x-intercept therefore `(-4, 0)`
