Answer:
To solve for y, you want to use the distributive property
First you want to distribute the 8 through the 3y-5 and the 9 through the y-5
8(3y-5)= 24y-40
9(y-5)= 9y-45
24y-40=9y-45 (get the x on one side, so first add 40 to each side)
24y=9y-5 (now subtract 9y to each side)
15y=-5 (divide both sides by 15)
y= -5/15= -1/3
Hope this helps ;)
Answer:

Step-by-step explanation:
In order to solve for a slope, you must in the formula,

<u><em>(In this case, you can choose which point can have the x(1) and y(1) and which can have the x(2) and y(2)</em></u> )
1.) Plug the numbers for x(1), x(2), y(1) and y(2)
2.) Solve and simplify the number, which you should get

150 - s <== ur expression
when s = 27.13
150 - 27.13 = 122.87
when s = 55.14
150 - 55.14 = 94.86
X=30 400+50 equals 450 so 450 divided by 15 is 30 reverse the operation
