Question

What is the slope of a line that passes through the point (−2, 3) and is parallel to a line that passes through (3, 7) and (−2, −8)? (4 points)

Answer 1

y = 3x + 9

Answer 2

find the slope between (3,7) and (-2, -7) using (y1-y2)/(x1-x2) = m

use that slope and plug it into point-slope form:

y-y1=m(x-x1)

where x1,y1 are the coordinates of the given point.

Answer 3

still confused

Answer 4

can you calculate the slope between (3,7) and (-2,-8) as i described?

Answer 5

m = slope

Answer 6

i still dont' understand why m stands for slope? was slope named something different before?

Answer 7

mlope?

Answer 8

:)

Answer 9

omg i just dont understand at all

Answer 10

okay... see these two point: (3,7) and (-2,-8)

they have an x coordinate (the first number) and a y coordinate (the second number)
subtract the second number from each point and divide the difference of the x coordinates.

Answer 11

second numbers (y coordinates) -8, 7. subtract them: -8 - 7 = -15
first numbers (x coordinates): -2, 3. subtract them: -2 - 3 = -5

divide them: -15/-5 = 3
that is your slope.

Answer 12

any help?

Answer 13

yes thank you :)

Answer 14

ok.. with that, you need to put it in poin-slope form: y - y1 = m(x - x1)
you already have your slope m = 3. the given point is (-2, 3). just plug those values in to the formula i just stated.
