What is the equation of the line that is perpendicular to the given line and passes through the point (5, 3) ?

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the figure, the line goes through the following points:

We found the slope:

By definition, if two lines are perpendicular then the product of their slopes is -1:

Thus, the equation is of the form:

If the line goes through we have:

Finally, the equation is:

Algebraically manipulating we have:

Option A

b and c

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
