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

Can you find the slope of the line that passes through (2, 13) and (−4, −11)?

Answer 2

thats the thing i dont know how to. i dont have my notes with me

Answer 3

This is essential knowledge that you need to memorize as long as you want to continue your math study:
slope m = Δy/ Δx

Answer 4

Can you calculate now?

Answer 5

so m= 13y/ -4x ?

Answer 6

x=2

Answer 7

I mean:
Δy = 13 - ( -11 ) = ..
Δx = ...

Answer 8

x= 24

Answer 9

NO, Δy = 24 ( not, x = 24)
Now similar Δx = ...

Answer 10

im sorry with math im slow. so its y=24. but what do you mean now similar ?

Answer 11

Similar means use Δ to find the difference ( subtraction):
Δy = y1 - y2 = 24
Δx = x1 - x1 = ...?

Answer 12

x= 6

Answer 13

Yes,
m = Δy/ Δx = ....?

Answer 14

/ symbol gets me confused, do i mult. or divide.

Answer 15

so i got =6

Answer 16

again, the distance Δx = 6

Answer 17

Now slope means the fraction between Δy / Δx = ....?

Answer 18

but i divided the x &&y so how can i fraction them out?

Answer 19

24?

Answer 20

4

Answer 21

x= 6*

Answer 22

Then m = Δy / Δx = ... ?

Answer 23

lol. soo the slope is 4? because i divided the y&&x

Answer 24

y= 24 x= 6

Answer 25

AGAIN, m = Δy / Δx
= 24/ 6 = 4
You will be confused forever if you don't learn the right notation from now on!
