Question

find the slope of the line passing through each pair of points
A. (-3 -1) and (-1 5)
B. (3/4, 5) and (5/4, 2)

Answer 1

Lets do a first.
To find the slope, do:
-1-5/-3+1
Simplify that, and you get:
-6/-2, which is 3.
Did you understand it?

Answer 2

some of it i think i need more help @zeinas.

Answer 3

how did you change the signs of the numbers and why? @zeinas. that's confusing me and also how would i do it if there are fractions in the equation such as question B)

Answer 4

So to find the slope, the equation is
y1-y2/x1-x2
now let's do the second one,
y1 and y2 is 5 and 2, so we have:
5-2/
x1 and x2 is 3/4 and 5/4 Let's use decimals. So we have now:
5-2/0.75-1.25
Simplify:
3/-0.5
So you're slope is -3/0.5 or -6.
Did you understand it?

Answer 5

yes i do know thank you very much @zeinas. best instructor or teacher ever!

Answer 6

In one, I changed the sign because it was :
-1-5/-3-(-1)
and - times - is positive so
-1-5/-3+1
Then I just simplified like I showed before.

Answer 7

And thank you :)
