Question

on 2 (1 point)

e abcd has the following vertices: a(0, 0), b(3, 4), c(-1, 7), and d(-4, 3).

is the slope of diagonal ac?

/7

7/1

1/7

/1

Explanation:

Identify the coordinates of points A and C

$$ A(0, 0),\quad C(-1, 7) $$

Apply the gradient formula

$$ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7 - 0}{-1 - 0} = \frac{7}{-1} = -7 $$

Match with the given options

$$ -7 = -7/1 $$

Answer:

• (A) -1/7
• (B) -7/1 (Correct answer)
• (C) 1/7
• (D) 7/1
