Answer:
B) -3
Step-by-step explanation:
The sum of the three angles of any triangle is equal to 180 degrees.
180-50-87 = 43.
43 = x+46
x = 43-46
x = -3
Y-intercept =12
Slope : y2-Y1/x2-x1
8-10/2-1
Slope : -2
I do not believe so but dont quote me on it.
2x-y=-5
-x-y=10
3x=-15
x=-5
-10-y=-5
-y=-5+10
-y=5
y=-5
