Answer:
Step-by-step explanation:
First, find the slope of the line:
The formula for finding the slope is:
Plug in the points:
= =
So now the equation is y = x + b
Now solve for b by plugging in one of the points:
(2,7)
y = x + b
7 = 2 + b
7 = + b
b =
So the equation will be
The answer is 6 whole number and 3\4 cannot be the whole number.
The tip would increase by $0.44. If you find how much the tip would be originally and compare it to the tip after the coupon is used, it would be $9.76 - $9.32 = $0.44. Richards method would give an extra $0.44 as a tip.
When you solve fractions and you end up having an improper fraction so you simplify. So you get a mixed fraction. So to convert an improper fraction to the mixed one you simply divide the numerator by denominator. simple.
