1.
A ray starts out at a point and continues off to infinity.
Symbol of the ray with a beginning point in X and passes through point Y is:
Therefore your answer is
2.
Symbol of a line passing through points A and B is:
Therefore your answer is
A+b=-10
ab=-75
a=-75/b
-75/b + b = -10
-75/b + b²/b = -10b/b
b²+10b-75=0
(b+15)(b-5)=0
b+15=0 or b-5=0,
b= -15, a=5
