30(-2/5)²(5/8) = 30*(4/25)*(5/8) = 30*4/(5*8) = 3
A) (0,0) and (3,1)
1-0 divided by 3-0
Slope is 1/3
the slope represents the relationship between x and y
b) (6,2) and (-3,-1)
-1-2 divided by -3-6
Slope is 1/3
c) yes, the two triangles represent the same slope as all of the four points used are collinear (on the same line), making all the slopes equal.
The slope is 4/3.
I hope this helps :)
