Call Emily's age is x, we have:
x * (x - 2) = 440
So x = 22
So Emily's 22 years old, Alysson's 20 years old.\\

Y = -3(2) +22
Y = -6 +22
Y = 16
Y = mx + c is the general equation of a line. m is the slope and c is the y intercept, by substituting these values in you get y = 1/4 x -2
X > -4 is the answer if you solve for x.
