Question

what is the slope of (3,3) and (-1,-1)

Answer 1

\[m =\Delta y/\Delta x\]

Answer 2

hey,
let x1=3 and y1=3
x2= -1 and y2 = -1
then use the formula, slope(m) = y2-y1/x2-x1= 1

Answer 3

use the formula y=mx + b after poulami's formula

Answer 4

so what is the answer?

Answer 5

m=(3-(-1))/3-(-1))=4/4=1

Answer 6

Slope is 1

Answer 7

what is the slope for (-3,1) and (1,5)

Answer 8

Work it the same way.
What are your two y values?

Answer 9

1,5

Answer 10

right, what is the difference between those points, 5-1=???

Answer 11

5-1=4

Answer 12

Yes, 4 is the numerator. Now work out the denominator. What are the x values?

Answer 13

-3-1=-2

Answer 14

Almost. The difference between -3 and +1 if you were at -3 how many units would you have to move to get to +1. We are trying to get the distance from -3 to +1

Answer 15

-3 - 1=-4

Answer 16

so the answer is 4/-4

Answer 17

1-(-3)=1+3=4

We have to go the same direction we went with the y value

Answer 18

so the answer is 4/4 or 1 again.

Answer 19

the slope for (-1,-1) and(3,3) is the slope 2 and 4

Answer 20

What you must do is to label your two points (in your mind) as P1 and P2\[m=(y _{2}-y _{1})/(x _{2}-x _{1})\]

Answer 21

Which point do you want to call P1?

Answer 22

O.K. I will make the assignment (-1,-1) is P1, then (3, 3) is P2
then slope m=(3-(-1))/(3-(-1))=4/4=1
slope is 1

Answer 23

(-3,1) (1,5) (3,3) (-1,-1) all these sides are each what
