20 x 18 x 5= 1,800
20 times 18 equals 360, then you mutiply 5 and get 1,800
If you have any questions about slope point formula...feel free to leave comments :)
I think it's a rational number.
Y will equal 36. You can figure this out because you know y is double the value of x. If x is 18,you can just multiply it by 2, which equals 36
