Y=2/3x-3. Follow the formula y=Mx+b. M is the slope, and b is the y intercept.
X=30
Put in proportions x/45 = 18/27.
Cross multiply and get 27x= 45 x 18
Or 27X = 810.
Next, divide by 27 on both sides to get X=30.
(0,0) means the origin of the coordinate plane and its when bothe the x and y xoordinates are 0
