Answer:
The slope is 2
Step-by-step explanation:
Given
x y
2 3
5 9
Required
Determine the slope
First, we have:


The slope is then calculated as:

This gives:



<em>Hence, the slope is 2.</em>
I think b.3 i am not sure but it should be b
4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
X=8.4

Y-9 =2/3 (x-3)
Y-9=(2/3)x - 2
Y=(2/3)x + 7
Heres some formulas...</span>
