X= 2 y= 3
x=4 y= 3
The slope is 0 since y doesn't change.
If this occurred over a span of 35 years and the population doubles every 7 years, we can divide 35 by 7 to find how many times the population has doubled, which would be 5 times. If we divide 60,000 by 2 (or multiply by 1/2) 5 times, you would get the answer, which would be 1,875.
Well, the only thing you have to do is use like terms. As you can see, you have 4x and 7x. These two are like terms because they both have the same variable. Just like 3y and 1y.
