The y represents the distance, remember time is the independent variable and distance is the dependent variable.
Another tip, when you see the title, such as distance vs time squared. The first term in the title always goes for the y axis and the second goes for the x axis.
I hope this answers your question!
Answer:
B. One solution.
Step-by-step explanation:
The solution is the point where the lines intersect.
this is system of equations
2x + 5y = -1 times this one by 5 to make the y's opposite
-10x -25y = 5
10x - 25y = -5 (this is it times by 5, now add them)
__________
0 + 0 = 0
now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.
