Question

Choose the point-slope form of the equation below that represents the line that passes through the points (-6, 4) and (2, 0).

1. y - 4 = -1/2(x + 6)
2. y - 4 = 2(x + 6)
3. y + 6 = -1/2(x - 4)
4. y + 6 = 2(x - 4)

Answer 1

3 is the answer, because the slope is -1/2 and then y-y1= y+6. Also x-x1= x-4. hope it helps :)

Answer 2

Thanks! :)

Answer 3

np anytime

Answer 4

Could you help me with another question?

Answer 5

sure I'll try

Answer 6

Okay, here it is:
Given the equation y - 3 = 1/2 (x + 6) in point-slope form, identify the equation of the same line in standard form.

x - 2y = -12
y = 1/2 x
y = 1/2 x + 6
y = 1/2 x + 9

Answer 7

The only one in standard form is x-2y=-12, also I did the math and I think that is the answer.

Answer 8

Okay, thanks

Answer 9

Wait, it said to put it in point-slope form though

Answer 10

Oh...never mind, I read it wrong. Thanks for helping me!

Answer 11

np

Answer 12

I got the first question wrong, but that's alright

Answer 13

oh so sorry I got x and y mixed up

Answer 14

it should have been 2 sorry

Answer 15

That's okay, you still helped me with the second one :)
