The format of a line equation is y = mx + b
When two lines are parallel, their 'm' variables are equal.
Knowing this, the unknown line equation, so far, would look like this:
y = 9x + b
Since we know that the line equation goes through the point (2, 7)
7 = 18 + b
b = -11
y = 9x - 11
1 meter is 100 centimeters so do 200÷10 what does that leavr you with ? 20
The answer is 72 all u need to do plug in the numbers where the letters are
Let X = be the amount the amount that new customer will have to pay
X = 0.8P + 100
