Question

How do you write an equation of a line with the given slope and y-intercept m=4/5 b=2?

Answer 1

`y=(4x)/5+2`

Explanation:

Lines are written in the form `y=mx+b`, where `x` and `y` are points on the line, `m` is the slope, and `b` is the `y`-intercept. Since we're finding a general equation of the line, we don't have to touch `x` and `y` (which are general points).

We are told that the slope, `m`, is `4/5` and the `y`-intercept, `b`, is `2`. Since lines are expressed as `y=mx+b`, we just make substitutions to get `y=(4x)/5+2`.
