Choose the correct slope of the line that passes through the points (-4, 8) and (-3, -6).
Answer
0
14
7
-14

Answer 1

To calculate the slope of a line given two points, you use the rise/run formula, which is:

y2 - y1 / x2 - x1

Then you'll have your answer.

Answer 2

i know that, but i don't know how to do it.

Answer 3

That means -6 - 8 which is -14
Divided by -3 - -4 which is the same as -3 +4 = 1
-14/1 is -14

Answer 4

When two points are given in question like (5,6) (2,3) so when we are viewing the formula m=y2-y1/x2-x1 it means that we have to plug the values of our points in this formula:
In my given example 3=y2, 6=y1 / 2=x2, 5=x1 Now when I plug these values it will look something like this:

m =3-6/2-5 which will be equal to -3/-3 = 1

Answer 5

Out Slope in my given example = 1

Answer 6

oh okay , this is just hard for me to understand , but thanks .

Answer 7

when given two points in question, see those points like this (x1,y1) (x2,y2)
and you know the formula of finding the slope: m= y2-y1 / x2-x1
Just plug the points. It is really simple idea. If you are still not understanding this, I would say watch this video by Sal Khan ..

Answer 8

Yeah its just that one equation you have to remember "rise over run" meaning find the difference in the y-axes divided by the x axes. Although this does assume that you know how to add and subtract negative numbers in combination with positive numbers.

Answer 9

What did you get?

Answer 10

-14 if u still need it lol
