Which of the ordered pairs in the form (x, y) is a solution of this equation?
three x minus begin fraction y over four end fraction equals eleven
(3, –8), (4, 4)
a.
the first is not a solution, but the second is.
b.
both are solutions.
c.
the first is a solution, but the second is not.
d.
neither is a solution.

B. 

if you plug in the points you get for the first one
3(3) - (4/(-8)) = 9+2 = 11
and the second
3(4) - (4/4) = 12-1 = 11

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
