## anonymous one year ago HELP! Write the point-slope form of the equation of the line through the given points. through: (-3, -1) and (2, 4) Question 23 options: A.) y + 1 = -(x + 3) B.) y – 3 = x + 1 C.) y + 1 = x + 3 D.) y + 3 = x + 1

1. anonymous

I thought it was B

2. anonymous

$y-y _{1}=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\left( x-x _{1} \right)$

3. anonymous

you are not correct.

4. anonymous

it should start by y-(-1)i.e.,y+1 or y-4

5. anonymous

How would you get the x part?

6. anonymous

either x-(-3) i.e.,x+3 or x-2

7. anonymous

then find the slope as given above.

8. anonymous

So it's C?

9. anonymous

it is a guess or calculated

10. anonymous

anyway you are correct.
