Question

How do you find the slope intercept equation with slope -8 and y intercept (0,9)?

Answer 1

`(y - 9) = -8x`

Explanation:

The slope intercept form for a linear equation is self-explanatory; all you need is any point on the line and its slope. The general equation for this form is:

`(y - y_1) = m(x - x_1)`

In this equation, `y_1` is equal to the y-coordinate of your given point, `x_1` is equal to the x-coordinate of your given point, and `m` is equal to the slope. Since we have all three of these values, all we need to do is plug them in:

`(y - 9) = -8(x - 0)`
`(y - 9) = -8x`
