<h2>Step-by-step explanation:
The slope of a line given two points can be found by using the formula
<h3>where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-7, 1), and (-4, -3)
The slope is
<h3>We have the final answer as

Answer:
<h2>Step-by-step explanation:<em><u> The triangle is isosceles, meaning it has two twin sides, that make two twin angles, namely AB = BC, and the angles at A and C are twins as well. </u></em></h2><h2><em><u> </u></em></h2><h2><em><u>now, the AD segment, is an angle bisector, meaning it cuts the angle at A in two equal halves, so if say the angles are x° each, then the bisectors cut it in (x/2)°. </u></em></h2><h2><em><u> </u></em></h2><h2><em><u>now, we know ∡ADB is 110°, therefore its supplementary angle, in green, is 70°. </u></em></h2><h2><em><u> </u></em></h2><h2><em><u>recall that the sum of all interior angles in a triangle is 180°, thus Check out the photo below </u></em></h2>
