Question

(3,0),(-11,-15) slope

Answer 1

For this case we have by definition, the slope of a line can be found by the following formula:

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

Two points are needed through which the line passes.

According to the data we have:

$(x_ {1}, y_ {1}) :( 3,0)\\(x_ {2}, y_ {2}): (- 11, -15)$

Substituting we have:

$m = \frac {-15-0} {- 11-3} = \frac {-15} {- 14} = \frac {15} {14}$

ANswer:

The slope is $\frac {15} {14}$

Answer 2

Slope formula: y2-y1/x2-x1

Plug in: -15-0/-11-3 = -15/-14 = 15/14 = slope
