What is the slope of line segment AB?<br> A) 2/3<br> B) 3/4<br> C) 4/3<br> D) -3/4

Lunna [17]

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

Where:

$(x_ {1}, y_ {1})$ and $(x_ {2}, y_ {2})$ are two points through which the line passes.

According to the image we have:

$(x_ {1}, y_ {1}): (-5,3)\\(x_ {2}, y_ {2}): (3, -3)$

Substituting we have:

$m = \frac {-3-3} {3 - (- 5)} = \frac {-6} {3 + 5} = \frac {-6} {8} = - \frac {3} {4}$

Thus, the slope of the line is:

$m = - \frac {3} {4}$

Answer:

$m = - \frac {3} {4}$
