Based on the given parameters, the value of y is 45
<h3>How to determine the value of y?</h3>
The given parameters are
Slope = 3
Value of x = 15
The value of y is calculated as:
y = Slope * x
This gives
y = 3 * 15
Evaluate
y = 45
Hence, the value of y is 45

<h3>What is scientific notation?</h3>
A number in scientific notation is given by:

With the base being
.
For this problem, the expression is given by:

When two factors of a multiplication have the same base and different exponent, we <u>keep the base and add the exponents,</u> hence:

5 x 4.2 = 21, hence the expression is:

When we divide two terms with the same base and different exponents, we keep the base and subtract the exponents, hence:

Which is the simplified expression.
