Question

How do you write an equation of a line with slope -1/2 and y-intercept -5?

Answer 1

`y=-1/2x-5`

Explanation:

The standardised equation for a straight line is `y=mx+c`

Where `m` is the gradient and `c` is the y-intercept.

So directly from the information in the question:

slope (gradient) `->m=-1/2`
y-intercept `->c=-5`

So `y=mx+c " "->" "y=-1/2x-5`
