Answer: 4/D
Step-by-step explanation: going through the options one by one.
for the first point, the first statement is true since both lines intersect at (4,5)
for the second point, this is also true because since (4,5) is on both functions, x=4 and y=5 will be a solution for both
for the third point, this is also true since the point of intersection is (4,5), this is the solution for the system
for the fourth point, this is untrue. since we don't know what f and g are and the only solution to the system is (4,5), what works for f may not necessarily work for g. so 4/d is the answer.
ps. you got this :) you'll be done before you know it
