Question

How do I interpret the graph of a linear function?

Answer 1

Linear functions have a degree of 1.

Examples:

`2x+3y=9`
`y=4x+7`
`y=1/2x`

If the linear function is in slope intercept form, `y=mx+b`, then `m` indicates the slope and `b` indicates the y-intercept.

If the linear function is in standard form, `Ax+By=C`, then the slope is found by the quotient, `-A/B`.

If you want to find the x-intercepts substitute in a value of 0 for the `y` variables.

If you want to find the y-intercepts substitute in a value of 0 for the `x` variables.
