Answer:
1 = 39 degrees (some theorem, like triangles sharing a bisector or something sorry)
3 = 51 degrees (if 1=39 and 2=90 degrees since its on a right angle, and a triangle's angles add up to 180, then you subtract 1 and 2 from 180 and get 51

Represent as an equation;

Expand the above

<em>Recall that b = $10 ----given</em>
becomes


(-9, -1)
(-9,-1) . -1 because that is the y intercept from the equation.
-9 because when you substitute -2 for x, and multiply by 4, you get -8. Then you subtract one, making the x value -9.
Therefore, the ordered pair of the solution is (-9,-1)
