The points (4, -11) and (8, r) lie on a line with slope 2. Find the missing coordinate r.
1 answer:
Answer:
The answer to your question is r = -3
Step-by-step explanation:
Data
A (4, -11)
B (8, r)
slope = m = 2
r = ?
Process
1.- Use the slope equation to find the coordinate r.
Formula
Substitution
= 2
2.- Simplify
3.- Solve for r
Multiply both sides by 4
Simplify
r + 11 = 8
Subtract 11 in both sides
r + 11 - 11 = 8 - 11
Simplify
r = -3

<u>Step-by-step explanation:</u>
We know from the question that the student earned $12.50 <em>per hour</em>.
Using this information, we can say that if the student worked for <em>h </em>hours, they would make a total of 12.50 × <em>h </em>dollars.
We also know that the total money they earned is $2500.75.
∴ Therefore, we can set up the following equation:
From here, if we want to, we can find the number of hours worked by simply making <em>h</em> the subject of the equation and evaluating:
<em>h </em>=<em> </em>
= 200.6 hours
