Ratio equivalent to 2:9 is 4:18, 6:27
If you multiply the same number to both numbers, the ratio would always be the same.
Slope = (5 + 4)/(2 +1) = 9/3 = 3
y = mx + b
5 = 3(2) + b
b = -1
equation
y = 3x - 1
answer
y = 3x - 1
That is true because as you can see in the other 2 equations, they both have z on one of the sides meaning that the sides that don't have z are equal to each other
