This is currently your equation since you do not know "b"
y = 2/3x + b
To find "b" you plug in the point (4,2) into the equation.
y = 2/3x + b
2 = 2/3(4) + b
2 = 8/3 + b (subtract 8/3 on both sides to get "b" by itself)
2 - 8/3 = b (make the denominators the same)
6/3 - 8/3 = b
-2/3 = b
So: y= 2/3x - 2/3
Answer:
Part A would be the answer A because it is $7.50 per book which means we will have to multiply
Step-by-step explanation:
Part B, if the camp leader has 12 campers that means she will need to buy books for each (12 x 7.50) which will give you a total of $90
That's easy when you estimate you are finding the whole number of which the decimal is closest to. When you place the decimal you count all the numbers behind the decimal point on the other numbers.
Then you move the decimal don that very spot.
Answer:
D
Step-by-step explanation:
y equals 1. x equals 15. 15 over 15 is 1.
