Notice that both the points, $(-7,-6)$ and $(-3,-5)$ , are on the line. So we can use those points to calculate the slope. Recall that that slope of the line $m$ can be calculated by $\frac{y_2 -y_1}{x_2 -x_1}\\$ if we have the points, $(x_1,y_1)$ and $(x_2,y_2)$ .

<h3>Calculating for the slope of the line:</h3>

Given

$(-7,-6)$

$(-3,-5)$

$m = \frac{-5 -(-6)}{-3 -(-7)} \\ m = \frac{-5 +6}{-3 +7} \\ m = \frac{1}{4}$

To simplify the expression, we distribute terms accordingly. It is done as follows:

<span>(3a – 4b)(a + b)
3a</span>² + 3ab -4ab -4b²
3a² - ab -4b²

Therefore, the correct answer is option A, <span>3a^2– ab – 4b^2.
