Y= -5/3x + 2
To find slope:
-8-7 / 6 - (-3) = -5/3
Plug in x and y from one of the points to the equation to find b
7 = -5/3 (-3) + b
B = 2
Put it all together:
y = -5/3x + 2
3%=0.03
You have to move the decimal to the right two times & you get 0.03
The Answer is x=15. Good luck!
The answer to 4-6 is negative 2
