Well your line travels parallel to the y axis. What's perpindicular to the y axis? The x axis. So all lines perpindicular to the line traveling vertically through (4, 0) are parallel to the x axis. Now we need to find the intercept of this line, which they give you as (-2, 3).
A horizontal line that passes through -2, 3? We can put this into an equation and see what happens.
y - y1 = m(x - x1)
y - 3 = 0(x - (-2))
y - 3 = 0
y = 3
Answer: The salon charges $16 for a manicure and $25 for a pedicure.
Step-by-step explanation:
Let x represent the amount charged by the salon for a manicure.
Let y represent the amount charged by the salon for a pedicure.
Over the weekend, they performed 49 manicures and 16 pedicures, bringing in a total of $1,184 in receipts. It means that
49x + 16y = 1184- - - - - - - - - - 1
So far this week, they have administered 31 manicures and 33 pedicures, with receipts totalling $1,321. It means that
31x + 33y = 1321- - - - - - - - - - 2
Multiplying equation 1 by 31 and equation 2 by 49, it becomes
1519x + 496y = 36704
1519x + 1617y = 64729
Subtracting, it becomes
- 1121y = - 28025
y = - 28025/- 1121
y = $25
Substituting y = 25 into equation 1, it becomes
49x + 16 × 25 = 1184
49x + 400 = 1184
49x = 1184 - 400
49x = 784
x = 784/49
x = $16
