Question

someone help!
find the slope of the line that passes through the points (5,8) and (9,4)

A. 3
B. 1
C. -1
D. 4/3

Answer 1

do you know the slope formula ?

Answer 2

I THINK Y=MX+B

Answer 3

ACTUALLY IDK

Answer 4

that is the equation formula with slope m ...you need the slope formula

m = (y2 - y1)/(x2 - x1) ...with 2 points given ...(x1,y1) and x2,y2)
can you try ?

Answer 5

here is the slope form x1 = 1, y1 = - 4, x2 = -4, and y2 = 2

Answer 6

no, your 2 points are : (5,8) and (9,4)

Answer 7

ya so dont i take 5-8 amd 8-4

Answer 8

i mean 4-8/9-5

Answer 9

so -1 is our answer right?

Answer 10

put in parentheses :) or else your computation will not work, can you try again and see what you get ?

Answer 11

correct ...but the way you typed there ...it's \[4 - \frac{ 8 }{ 9 } - 5\]
and this won't come out -1 :)

Answer 12

yay!

Answer 13

(8-4)/(5-9)=-1
