It's a because the form is y-y1=m(x-x1) and of you put the given information in it will be y+1=-(x+10)
Answer: 44 degrees.
Step-by-step explanation: Since the sum of the measures of the angles in a triangle add up to 180 degrees, we can figure out the measure of the third angle by adding the first two angles and subtracting the sum from 180. 102 + 34 = 136. 180 - 136 = 44, so the measure of the third angle is 44 degrees.
B if you need an explanation just comment
It's 3/4 because (y2-y1)/(x2-x1)
