Y=mx+b
m=slope
paralell lines have the same slope
y=1/2x+3
m=slope=1/2
the slope of the paralelll line is 1/2
Since this is about finding the relative value of one parameter to another, our approach of solving this problem is by finding the ratio. In this way, we can compare the degree of their difference.
Ratio = Diameter of ball/Diameter of neuron
Ratio = 0.04 m/5×10⁻⁶ m
Ratio = 8,000
Therefore, the tennis ball is 8,000 times larger than the neuron,
Answer:

Step-by-step explanation:
When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.
Sample solution:



Answer:
0.25 per gallon
slope: 0.25
Step-by-step explanation:
the train travels 25 miles per 100 gallons
this simplifies into 0.25 per 1 gallon
slope is y/x
y/x = 25/100 = 0.25
