Equations based on given, 48 coins, total of $6 = 600c:
x + y = 4825x + 5y = 600Substitute y in the second equation, y = 48 - x
25x + 5(48 - x) = 60025x + 240 - 5x = 60020x = 360x = 18Then value of y is:
y = 48 - 18 = 302) Similarly to problem 1.
x + y = 2025x + 5y = 260Substitution: y= 20 - x
25x + 5(20 - x) = 26025x + 100 - 5x = 26020x = 160x = 8Then finding y:
y = 20 - 8 = 12If y=32 when x=8, find y when x=30.

slope =-5, y-intercept =-2
Answer:
y = -5x - 2
Step-by-step explanation:
y = mx + b
m = -5
b = -2
Step-by-step explanation:
I am not completely sure what your question is, but if you want to write an equation, you can just plug in the values for m and b to get y=-5x-2. If you wish to graph it, start at (0,-2) because that is your y-intercept. Next, move up 5 units and to the left 1 unit since the slope is negative. Now you have the point (-1,3). Connect the dots to get the graph.
