You first use the Y intercept to know the y value is 3 when the x values is zero. The rest of the information can be identified if in between each increase in the x term, there was a decrease in the Y term by 4 units
Answer:
a = 9h + nb
Step-by-step explanation:
1) Variables:
a=total amount earned
h=hours worked in one week
n=number of items repaired
b=bonus amount for each item
2) He earns $9.00 an hour plus a bonus for each item repaired.
=> he earns 9 times the number of hours plus value of the bonus times the number of items repaired
=> a = 9h + nb
Use the Pythagorean theorem (a^2 + b^2 = c^2)
7^2 + 24^2 = x^2
x^2 = 625
x = 25
