Question

question 7 (1 point)

a quadrilateral is drawn on the coordinate plane with the following coordinates: a (0, 0) b (3, 4), c (-1, 7), and d (-4, 3).

what is the slope of ab?

-3/4
3/4
-4/3
4/3

Explanation:

Identify coordinates of points A and B

$$ A = (0, 0),\quad B = (3, 4) $$

Apply the gradient formula

$$ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 0}{3 - 0} = \frac{4}{3} $$

Answer:

• (A) -3/4
• (B) 3/4
• (C) -4/3
• (D) 4/3 (Correct answer)
