Y = kx, so y/x is constant
you want y such that
y/12 = -2/-8
Hello!
Slope formula:
y2-y1/x2-x1
y2: 8
y1: 1
x2: -7
x1: -6
Plug given values into the equation:
8-1/-7 - (-6)
Subtract
7/-1
Divide
-7
The slope is -7
For the 60°'s topmost line, you can find the angle next to it is 120° because it's a straight line. You can do the same for 95° if you put that the angle opposite it is equal already because it's the opposite angle, so you subtract from 180° again to get 85°. When you extend the lines, you can find the alternate interior angles to the 60° and 85°, which are congruent to them. You then get that for both the formed triangles there is one 85° and one 60°, which together with one more angle should equal 180°. Through knowing that the sun of the triangles angles should be 180°, if you subtract the sum of 60° and 85° from 180°, you get the angle of the 3rd angle in the triangles (35°). This angle also forms 180° with x on a line, so 180°-35°=x, which is 145° seemingly.
