This week I learnt the different types of equation that represents lines on a graph and how to transform from one form to another. The slope-point form is an easy way of finding the equation and the line First you need the slope and one point of the line to do it. Then put the […]

Math 10 – Week 15 – Slope Equations
There are three types of equations for slopes, Point slope form, Slope y-intercept form, and general form. Point slope form is m(x-x2)=(y-y2). Slope y-intercept form is y=mx+b. General form is ax+by+c. General form has an extra rule, A should always be positive. Each form can be translated into the other except for changing other forms […]
Math 10 – Week 14 – Slopes
In this week, we learned how to find the slope using a graph or coordinates. there are four types of slopes there is a positive slope, negative slope, zero slope and an undefined slope. the positive slope starts on the bottom on the left and goes up with a slope right. The negative slope is […]
Math 10 – Week 13 – Function Notation
Function notation is used to replace the mapping notation ( to ) Under a function “f” is denotated by f(x), which is read “f of x”. In the function above f can be defined by the formula, this is called function notation.
week 12 – math 10 – Functions
This week, we learned functions. We looked that they are a very special relationship. For example: “a function is like your biological mom, because you can have just one biological mom. And a friendship is like a relation, because you can have more than just one friend.” Like how an input has one output. […]
Math 10 Week 11- Intercepts
This week, we learned about finding X and Y intercepts. The first thing to do is remind yourself when finding an X intercept is that Y will always equal zero. So therefore whatever Y multiplies by will automatically be zero. So then once that’s gone we are left with 3x = 30 and the next […]
Math 10 – Week 10 – Ugly Polynomials
In this week, I learned how to factor the ugly polynomials. Ugly polynomials is a type of trinomial that is harder to factor, so it can’t be solved with basic techniques that we learned before. If a polynomial is Ugly then it has a term in front of the first trinomial pattern ( # ). If […]
Week 6 – Math 10 – Area Model
Area model is my favorite way to multiply polynomials, because it’s a easy way to don’t make mistakes. So first, according to your product you will draw like a rectangle and put all the values on the top and in the left side. Now you just want to make sure to multiply everything and that […]
Week 5 – Math 10 – Algebra Tiles
In the week 5 of Math 10, I learned about Algebra Tiles. It’s something that I didn’t knew before, so everything is basically new to me… but it’s not that hard. So, in Algebra Tiles, you’ve 3 geometric forms: a big square, a rectangle and a small square. The big square represents (x2), the rectangle represents […]
Week 4 – Math 10 – Inverse Trigonometric Functions
What I learned in week 4 was Inverse Trigonometric Functions, which was nice because in Brazil we just study “regular” Trigonometric Functions. The idea is the same in trigonometry. Inverse trigonometric functions do the opposite of the “regular” trigonometric functions. For example: Inverse sine (sin–1), do the opposite of the sin; Inverse cosine(cos -1), do the […]
