Question

How do you find the slope , y intercept, and x intercept of the line y - 3x=7?

Answer 1

Slope is 3
y-intercept is 7
x-intercept is -7/3

Explanation:

Get the equation into the form `y=mx+b` by adding `3x` to both sides of the equation. You get
`y=3x+7`

The slope is `m`, which is the coefficient of `x`. In this case, it is `3`.

The y-intercept is `b`, which is positive 7 in this case. The y-intercept is when `x=0`, so you could also substitute that into the equation.

The x-intercept is when `y=0`, so use the equation to figure out the x-intercept.

`0=3x+7`
`-7=3x`
`x=-7/3`
