- minus hes purchusing so hes losing money
Don't repost because somebody will answer (probably)
we got some points
normally it is like
y=mx+b
find m and x
if we assume they are in a straight line
m is slope and b is y intercept
ok so we see the slope betwee (6,11) and (3,5) is 2
because slope between (x1,y1) and (x1,y1) is (y2-y1)/(x2-x1)
y=2x+b
if we solve for b we get
hmm
5=2(3)+b
5=6+b
-1=b
y=2x-1
so double x and minus 1 to get y
10*2=20, 20-1=19
23=2x-1
24=2x
12=x
the missing points are 19 on right side and 12 on left
rule is y=2x-1 or
2x-y=1

Solve graphically
First, we need to determine the inequalities of the system.
For number of coins, we have:
because the number of coins is not less than 20
For the worth of coins, we have:
because the worth of coins is not more than 0.80
So, we have the following equations:
Make y the subject in both cases:
Divide through by 0.01
The resulting inequalities are:
The two inequalities are plotted on the graph as shown in the attachment.
--- Blue
--- Green
Point A on the attachment are possible solutions
