There are a few different ways to define a linear function. We will be using the idea that linear functions are of the form f(x)=mx+b where both a and b are real numbers. This is a very basic question, but thinking it through can be tricky. The important thing is that we stick ...
Example 1: If2y – 5 = 13,what is the value ofy? Solution: The given linear equation is: 2y – 5 = 13 ⇒ 2y – 5 + 5 = 13 + 5[Add 5 on both sides] ⇒ 2y = 18[Simplify] ⇒ y = \( \frac{18}{2} \)[Divide by 2 on both sides] ...
If you're learning about graphs, you're bound to see a bunch of linear equations, so it's a good idea to understand what makes an equation a linear equation. This tutorial explains linear equations and shows you the difference between equations that are linear and ones that are not. Check...
Some key applications of parsers involve repeated iterations of a given expression at different values of the variables involved. Iteratively determining the roots of an equation, graphing etc. For repeated iterations of an expression over a value range, say 'x^2+5*x+1', the wrong usage would...
Linear regression: Linear regression algorithms take data points and build a mathematical equation for a line that best supports predicted outcomes. This is sometimes known as the “line of best fit.” Linear regression works by tweaking variables in the equation to minimize the errors in prediction...
