Answer:
a is a value of 5 and b is is equal to 9
Step-by-step explanation:
all you have to do is get 16 and 4 by them self and take them out, and find the remaining numbers
i don't know if there is a graph for this problem, but m1 should always equal m2
if m1 and m2 are parallel, one line that is perpendicular to m1 is always perpendicular to m2, and the slopes of m1 and m2 are equal and their lines should never intersect
