The y intercept is when x=0
0+5y=-10
y=-2
So first create and define your variables:
Z = amount of zebra fish
N = amount of neon tetras
Now create your equations:
2z+2.15n=31.20
z+n=15
This is your system. There are multiple methods to use but in this problem I’ll use the substitution method by simplifying the bottom equation.
2z+2.15n=31.20
z=15-n
Now I’ll plug the bottom equation into the top one.
2(15-n)+2.15n=31.20
And just solve from here.
30-2n+2.15n=31.20
0.15n=1.20
n=8
So he bout 8 neon tetras, and 15-8= 7, so he bought 7 zebra fish

Step-by-step explanation:
Given

The equation is incomplete. However, a possible question could be to calculate the distance of the fish at a particular time
e.g. Time, t = 4,
The distance is:




Another possible question is to determine the time taken to cover a certain distance
e.g.
Distance, y = 400
This gives:
