The standard form:
The point-slope form:
m - slope
The formula of a slope:
We have the points (6, 1) and (5, 4). Substitute:
<em>use distributive property</em>
<em>add 1 to both sides</em>
<em>add 3x to both sides</em>
The mathematical expression for the given statement is 50 + 10x
<h3>How to write a mathematical expression for this statement?</h3>
The given parameters are:
Initial distance = 50 laps
Rate of increment = 10 laps each week
Represent the number of weeks with x
So, we have:
Number of laps = Initial distance + Rate of increment * Number of weeks
This gives
Number of laps = 50 + 10 * x
Evaluate
Number of laps = 50 + 10x
Hence, the mathematical expression for the given statement is 50 + 10x
