Question

How many forms of linear equations are there?

Answer 1

I have heard of four

Explanation:

Slope-intercept form: `y=mx+b`, where `m` is the slope and `b` is the y-intercept

Standard form: `ax+by=c`

Point-slope form: `y-y_1=m(x-x_1)`, where `m` is the slope and `(x_1, y_1)` is a point on the line

Intercept form: `x/a+y/b=1`, where `a` is the x-intercept and `b` is the y-intercept
