Question

How do you find a standard form equation for the line with slope -3 that contains the point (6,8)?

Answer 1

`3x +y =26`

Explanation:

According to the slope point form,

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

`y-8 = -3(x-6)`

`y-8 = -3x+18)`

`3x +y -8=18`

`3x +y =26`

Standard form is `ax + by =c`
where `a, b and c` are integers and `a >0`

General from is `ax +by + c =0`
