Why Math?
Why Math you ask?
Math unlocks the wonders of logic!
Math is FUN!
Specifically...
Algebra 1: This studies the relationships between numbers and quantities so we can find the unknown.
Geometry: This is the study of shapes and their properties in our world and beyond.
Algebra 2: This cultivates problem solving and abstract thinking which are useful any field you will eventually have a career in.
Statistics: This is the study of data.
PreCalculus: This introduces and internalizes the rules and basic math needed for more fun (and higher level) mathematics.
Calculus: This is the study of change.
Why is slope "m" and y-intercept "b"?
Believe it or not, math used to be extra confusing when it was being discovered, so there was not a universally set notation for things. Variables were just letters that stood for an unknown, so they did not need to be specific letters for specific types of information. This lead to the use of letters in order, so the first linear equation was written as f(x)=ax+b where f(x) is the function notation for y. The "a" represents the slope because it is the coefficient of x; a french mathematician changed it to "m" in reference to the slope of a mountain, and that was seen and copied by so many people that most texts use it. The "b" represents the y-intercept because it is the constant; nobody decided to change it that caught on, so most text just use it that way. As a side note, this is why linear regression on the calculator can be done in two different ways and users should make sure to use the ax+b form.
