Question

1. Write the equation, in slope-intercept form, of the line with slope 9 and y intercept (0, --13).

Answer 1

`y=9x-13`

Explanation:

Slope-intercept form is
`y=mx+b`, where m is the slope, and b is the y-intercept. They tell us the slope is 9, so
`m=9`. They also tell us that the y-intercept is (0,-13), which means that
`b=-13`. Plugging both of those values in gives us the equation:

`y=9x-13`
