Question

Would I use point-slope form to solve this?

What is the equation of the line that passes through the points (-3, 2) and (-5, 8)?

3x - y = -11

3x + y = - 7

3x + y = 5

x + 3y = 3

Answer 1

first find slope:
m = ( y2 - y1) / ( x2 - x1)

Answer 2

8-2/-5--3

6/-2

slope -3

Answer 3

then use point slope formula:
(y - y1) = m (x - x1)

Answer 4

y-2=-3(x--3)
y-2=-3x-9

Answer 5

3x+y=-7 so B?

Answer 6

y + 3x = -7
rewrite it:
3x + y = -7
yes B

Answer 7

very good ! :)
