What is the slope of a line perpendicular to the line whose equation is y= -2/3x -5

Step-by-step explanation:

Hi there!

In the given equation, , the slope of the line is .

Perpendicular lines always have slopes that are negative reciprocals, like negative "flipped" fractions.

Example: The reciprocal of (which is the same as 2) is . The negative of is .

Example 2: The negative reciprocal of is .

Using this logic, we can determine that the negative reciprocal of is . Therefore, the slope of a line perpendicular to the line whose equation is would be .

I hope this helps!

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
