Slope = (y2-y1)/(x2-x1)
slope = (1-5)/(2-4)
slope = -4/-2
slope = 2
He will have 1/15 of a cup of apple juice per serving
For a) you could use 1/2y=1x and for b) y=2.5
5.50=0.10d+0.05n
70=d+n
how to solve-
n=70-d
5.50=0.10d+0.05(70-d)
5.50 = 0.10d +3.5 -0.05d
5.50= 0.05d+3.5
2=0.05d
d=40
70=d+n
70=40+n
n=30
there are 40 dimes and 30 nickels
