7. What is the y-intercept of a line that passes through the points (1.-7) and point (5,-25)?

1. 2.5
2. -2.5
3. 2

Y-int: (0,-5/2)
Which is -2.5

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
