What is the equation of the line that passes through (1, 3) and (-2, -3)?

m = y2-y1/x2-x1 -> -3-3/-2-1 = -6/-3 -> +2

y=mx+b or 3=2 × 1+b -> b = 1 (y-intercept)

y = 2x+1

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
