Question

What is the slope and intercept of `7x=5`?

Answer 1

`7x=5` is the equation of a vertical line and as such its slope is undefined.

Explanation:

`7x=5color(white)("XX")hArrcolor(white)("XX")x=5/7`

The value of `x` doesn't change no matter what vales are chosen for `y`
So the slope, defined as `("change in "y)/("change in "x)`
would require division by zero.
