Question

question 11 (1 point)
a quadrilateral is drawn on the coordinate plane with the following coordinates: a(0, 0), b(5, 5), c(6, 12), and d(1, 7).

what is the slope of cd?

7/1
1/1
1/7
none of these

Explanation:

Identify coordinates of points C and D

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

Apply the slope formula

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

Simplify the expression

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

Answer:

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