Question

Please help me I don’t understand this

Answer 1

When you're given a point and the slope of a line, it is often easiest to write its equation in point-slope form.

This is
`y-y_1=m(x-x_1)`, where
`(x_1,y_1)` is the ordered pair for the point you are given and m is the slope.

Here, you would write
`y-8=-3(x-7)`. Then, you simplify to get to slope-intercept form, which is
`y = mx+b`, where b is the y-intercept.


`y-8=-3(x-7) \\ y=-3x+29`

The correct answer is A.
