Question

What is the equation of the line through point (-1.5, 4.6) with slope 0?

Answer 1

`y=4.6`

Explanation:

The slop (gradient) is the amount of up (or down) for the amount along. So if the gradient is 0 it does not have any up or down. So it must be parallel to the x-axis.

If it is parallel to the x axis it is defined as `y= ("some constant value")`

So if `(x,y)-> (-1.5,4.6)` the value of x is of no consequence at all.

We have: `y=4.6` as the complete equation.
