Question

n 11 (1 point)

rilateral is drawn on the coordinate plane with the following coordinates: a(0, missing), b(missing, 5), c(6, 12), and d(1, 7).

is the slope of cd?

1

-1

7

one of these

Explanation:

Identify coordinates of points C and D

$$ C = (6, 12),\quad D = (1, 7) $$

Apply the gradient formula

$$ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 - 12}{1 - 6} $$

Simplify the expression

$$ m = \frac{-5}{-5} = 1 $$

Answer:

• (A) 1 (Correct answer)
• (B) -1
• (C) 7
• (D) none of these
