Answer: ? = -22.5

Step-by-step explanation:

Using a negative number to replace the ? turns the minus into a plus sign.

-21 - (-22.5) = 1.5 is the same as -21 + 22.5 = 1.5

Line CH contains points (-2, 6) and H(5, -3) What is the slope of G?

Xelga [282]

Answer:

The slope of line G is $\dfrac{- 9}{7}$ .

Step-by-step explanation:

Given as :

The points of the line CH contains

C = $x_1$ , $y_1$ = - 2 , 6

H = $x_2$ , $y_2$ = 5 , -3

Let The slop of line CH = G

<u>Now, slope of line is </u>

G = $\dfrac{y_2 - y_1}{x_2-x_1}$

i.e G = $\dfrac{- 3 - 6}{5 -(-2)}$

Or, G = $\dfrac{- 9}{5 +2}$

Or,G = $\dfrac{- 9}{7}$

So, The slope of the line CH = G = $\dfrac{- 9}{7}$

Hence, The slope of line G is $\dfrac{- 9}{7}$ . Answer
