Answer:

15) Slope (m) = -7/5

16) Slope (m) = 0

17) Slope (m) = 1/0 (It's an undefined slope, in other words it's just a vertical line)

Step-by-step explanation:

Use this formula for each, to find slope⤵⤵⤵

$\frac{y {2} - y1}{x2 - x1}$

15) ⤵

$\frac{10 - 3}{ - 1 - 4} = \frac{7}{ - 5} = - \frac{7}{5}$

16) ⤵

$\frac{ - 5 - ( - 5)} {2 - 3} = \frac{0}{ - 1} = 0$

17) ⤵

$\frac{ 3 - 2}{ - 5 - ( - 5)} = \frac{1}{0}$

Hope this helps :)

use your formula to determine the height of a trapezoid with an area of 24 square centimeters and base length of 9 cm and 7 cm

NikAS [45]

Answer

The height of the trapezoid = 3 cm

Explanation

The area of a trapezoid is given as

Area = ½ (a + b) h

where

a and b = base lengths of the trapezoid

a = 9 cm

b = 7 cm

h = height of the trapezoid = ?

Area = 24 cm²

Area = ½ (a + b) h

24 = ½ (9 + 7) h

24 = ½ (16) h

24 = 8h

8h = 24

Divide both sides by 8

(8h/8) = (24/8)

h = 3 cm

Hope this Helps!!!
