For this case we have that by definition, having two points through which a line passes $(x_ {1}, y_ {1})\ and\ (x_ {2}, y_ {2})$ , we can find its slope of the following form:

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

If we have:

$(x_ {1}, y_ {1}) = (5,7)\\(x_ {2}, y_ {2}) = (- 1,19)\\m = \frac {19-7} {- 1-5}$

We know that equal signs are added and the same sign is placed

$m = \frac {12} {- 6}\\m = -2$

So, the slope of that line is $m = -2$

Answer:

$m = -2$

An angle measures 16.4° less than the measure of its supplementary angle. What is the measure of each angle?

Answer:

Step-by-step explanation:

Let one angle = A

Let the other angle = B

A + B = 180

A = B - 16.4 Substitute for A in the top equation

B - 16.4 + B = 180 Combine the left

2B - 16.4 = 180 Add 16.4 to both sides

2B = 180 + 16.4

2B = 196.4 Divide by 2

B = 196.4/2

B = 98.2

A = B - 16.4

A = 98.2 - 16.4

A = 81.8
