Question

What is the slope of a line that passes through the point (−5, 3) and is parallel to a line that passes through (2, 13) and (−4, −11)?

Answer 1

all you need to do is find the slope of the line through (2, 13) and (−4, −11)

Answer 2

this is because parallel lines have equal slopes

Answer 3

@jim_thompson5910 this is a pretest question so I don't really know how to do that yet T_T can u help me please? :)

Answer 4

well if it's a pretest and you don't know it, then no big deal really

Answer 5

if you know it, then you can answer it and move onto a higher level (and not have to relearn it)

if you don't know it, then this will tell the teacher what you need to learn

Answer 6

so either way, it works in your favor

Answer 7

@jim_thompson5910 exactly :) but I wanna get it right ^-^ can u give me an example of how to do this or help me in someway at least? :)

Answer 8

I know you want to get it right, but it should be you that's doing this on your own

I'll give you the formula and little bit after that, but will stop there

Answer 9

The slope formula is

m = (y2 - y1)/(x2 - x1)

Answer 10

what this tells us is that the slope is equal to the change in y (y2 - y1) over the change in x (x2 - x1

Answer 11

thanks jim ^-^

Answer 12

use y=mx+b

Answer 13

you're welcome

Answer 14

you will know y and x cuzz it is given to you and you know m from jims formula and you will have to find b :D

Answer 15

also

(x1, y1) = (2,13), so we can say x1 = 2 and y1 = 13

(x2, y2) = (-4,-11), so we can say x2 = -4 and y2 = -11

I'll let you take over

Answer 16

thanks again jim ^-^ and thanks timo :D

Answer 17

sure thing
