20x = 60
x = 3 feet
choice (1.) is the answer
Answer:
C, y = 1.2x
Step-by-step explanation:
Notice that x, representing time, is multiplied by 1.2 each time to get y, representing the number of problems. You can find this out by dividing y by x. 36/30 = 1.2.
48/40 = 1.2.
And so on...
P.S.: If you ever come across a problem like this, subtract one y value by another y value, then subtract the corresponding x values from eachother, then make both numbers into one fraction with y as the numerator and x as the denominator. In this problem, that would look like this:
48 and 36 are both y values: 48 - 36 = 12
40 and 30 are the corresponding x values: 40 - 30 = 10
We get 12/10, which can be simplified to 1.2. The slope is 1.2.
This method will always work for a straight line and will be taught to you soon if you haven't learned it already.
