Question

How do you write the equation for slope 5; y-intercept (0,-2) and slope -3/4; y-intercept (0,8)?

Answer 1

1. `y=5x-2`
2. `y=-3/4x+8`

Explanation:

The standard form for a linear equation is `y=mx+c`
(Note: some textbooks show this as `y=mx+b`, but they are the same idea.)

The `m`, is the slope or gradient.

And the `c` (or `b`), is the y-intercept. For y-intercept the `y` value is the important one, (the second number).
