<h3>What is a straight line?</h3>A straight line is a combination of endless points joined on both sides of the point.
We have a straight line:
Convert it to the general form given below:
or
(Slope of AB line)
For the slope(m') of the PQ line:
( because AB and PQ are perpendicular to each other)
We know the:
Where (x', y') = (7, 6), we get:
(multiply by -1/2 on both sides)
Thus, the equation of the central street PQ is -1.5x - 3.5y = -31.5

Answer:
Rani can use the rented canoe for hours.
Step-by-step explanation:
Given:
Rani has at most $20 to spend on a canoe rental.
To rent a canoe $12.To use the canoe cost $3 an hour.
The number of hours is
Now, to find the number of hours rani can use the rented canoe.
Total money Rani has at most to spend = $20.
The rent of a canoe = $12.
The cost of using canoe per hour = $3.
<em><u>According to question:</u></em>
Now, to find the number of hours rani can use the rented canoe:
<em>Subtracting both sides by 12 we get:</em>
<em /><em />
<em>Dividing both sides by 3 we get:</em>
<em /><em />
<em /><em />
Therefore, Rani can use the rented canoe for hours.
