Question

What is the equation in point-slope form of the line passing through (-2, 0) and (2, 8)?
give a medal to first that answers

Answer 1

Ok Lets see here

Answer 2

First of all, you need to know the point-slope form equation.

point-slope form:
y1 - y2 = m (x1 - x2)

Then, find the slope of the line.

slope equation:
y1 - y2 / x1 - x2
8 - 3 / 2 - 3
5 / -1
-5

Next, plug in the coordinates in the right place.

x2:
2 or 3

y2:
8 or 4

plug-in:
y - 4 = -5 (x - 3)
y - 8 = -5 (x - 2)

And that's the equation you can use either coordinates if you'd like.

Answer 3

is that good enough lol

Answer 4

what do you think the answer is

Answer 5

i know what the answer is

Answer 6

jsut wandering what you think it is

Answer 7

ANSWER: y - 8 = -4(x - 2) or y - 4 = -4(x - 3)

Answer 8

not at all

Answer 9

wheres my medal

Answer 10

these are the possible answers
a. y = 2(x + 2)
b. y = 2(x - 2)
c. y = -2(x - 2)
d. y = -2(x + 2)

Answer 11

thats not the answer

Answer 12

ooooo ok got you one moment

Answer 13

Start by using the slope intercept form
y1-y2=m(x1-x2)

Then, leave y1 and x1 the same and plug in one of the coordinates: (-2,0)
y-0=m(x+2)

Next find m. m=slope. slope= change of y over change of x
0-8/-2-2 = -8/-4 = 2

your slope is 2. Plug that in for m.
y-0=2(x+2)

Simplify so you are in point slope form.

y=2(x+2)

A is your answer.
