Question

What is the point slope form of a line that has a slope of -4 and passes through point (-3,1)

Answer 1

Answer: it's B

Explanation:

I got it right on the test

Answer 2

The point-slope formula is:
`y-y_1=m(x-x_1)`

We know the slope is -4 and the ordered pair
`(x_1,y_1)` is (-3,1)

So plug it in:
`y-1=-4(x-(-3))`

`y-1=-4(x+3)`

That is the point slope form

You can simplify it further to slope-intercept form if you want to, which helps graph it in my opinion
