Remember you can do anything to an equation as long as you do it to both sides
a=age
500 reduced by 2 times a is equal to 388
500-2a=388
minus 500 both sides
-2a=-112
divide both sides by -2
a=56
you are 56
The equation is already is slope intercept form where you can easily point out the gradient, or the slope, and the y intercept.
y=mx+b where m is the gradient, and b is the y intercept.
Since there is no m, the gradient is 1.
The y intercept had x=0 and y=b
b in this case is 6
the y intercept= (0,6)
2:15+2:31=4:46
4:46+1:16=5:62=6:02
6:02+2:56 =8:56pm or 20:56
