Lines p and q are parallel.
Corresponding angles are congruent.
Each two adjacent angles are supplementary.
Vertical angles are congruent.
Angles 7 and 8 are adjacent, supplementary angles.
m<7 + m<8 = 180
m<7 + 115 = 180
m<7 = 65
Angles 6 and 8 are corresponding angles and congruent.
m<6 = m<8
m<6 = 115
Angles 1 and 6 are vertical angles and congruent.
m<1 = m<6
m<1 = 115
Slope = (y2-y1)/(x2-x1)
let y1= 2, y2=3, x1=-1, x2=-4
(3-2)/(-4-(-1))=
1/-3
-20w+15-2=-13w-10-4w+2
-20w+13=-17w-8
I gave you the basis of the question. Hope it helped. Hopefully you can solve the rest!
The slope of line is negative. Therefore, correct answer is D.
the answer a is 6 and b is 2
