Answer:

Step-by-step explanation:
To begin simplifying this, we can first divide the coefficients, giving us:

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

Now, simplifying this gets:

2/4 in simplest form:
First, to find the simplest form of a fraction, you'll need to find the greatest common factor (GCF). To do this, we can list the factors of 2 and 4 and find the first common one.
Factors of 2: 1, 2
Factors of 4: 1, 2, 4
Since 2 is our first common factor, it is our GCF.
Second, we can now take our GCF (2) and divide it with our numerator and denominator. We will get a new numerator and denominator.

Answer in fraction form:

Answer in decimal form:
Answer: The equation of a linear relationship is y = mx + b, where m is the rate of change, or slope, and b is the y-intercept (The value of y when x is 0).
