To know whether or not they are valid you would plug in the y that corresponds to the x with it.
For example,
(50,35)
35=0.5(50)+10
Multiply 50 with 0.5,
35=25+10
35=35
You would do the same for your others pairs, seeing if they all are valid. I think they should be.
Answer:
$3,150
Step-by-step explanation:
To find the sale price, multiply the original price ($3,500) by 0.90. This 0.90 comes from subtracting 10% from 100% and converting the result to the decimal fraction 0.90.
0.90($3,500) = $3,150
