Question

How do you write `4x - y-7 =0` in standard form?

Answer 1

`y=4x-7`

Explanation:

This is a linear equation so the standard from must be of the form `y=mx+c`.
In this case we may take the y across and write it as
`y=4x-7`

If we draw the graph of this function it would be a straight line of gradient 4 and y-intercept - 7, as shown below.
