Find the slope of (-2,-5) and (8,-5) and find the slope of the line passing through the points (4,9) and (4,-7)

Part 1)

Part 2) The slope is undefined

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

Part 1

we have

Substitute the values

 ----> is a horizontal line (parallel to x-axis)

Part 2

we have

Substitute the values

  ----> is a vertical line (parallel to y-axis)

The slope is undefined

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
