ke = 0.5 \times 20 \times  {5}^{2}  \\ ke = 10 \times 25 \\ ke = 250 \: joules
gpe = 20 \times 9.81 \times 2 \\ gpe = 40 \times 9.81 \\ gpe = 392.4 \: joules

1. 3x - 3y = 9  

to find the x or y intercept, multiply the other variable that you are not tryng to find by 0  

3x - 3(0) = 9             3(0) - 3y = 9

3x = 9                       -3y = 9

3x/3 = 9/3                 -3y/-3 = 9/-3

x = 3                           y = -3


2. I did the same thing for the rest

x = 6     y = -2


3.   x = 2.5     y = -5


4.  x = -4  y = -2/3
