Y result from something being multiplied by X , and the values are always proportional to one another . Notice that putting these points into a ratio of x - value to Y - value result in 1:3 as a simplified version . So , The constant of proportionality is what x is being multiplied by to get y . In this case , it is 3
3.5 cubic centimeters is also equivalent to 3.5 ml
Y = 5 x 3 + 8
y = 15 + 8
y = 23
