This week we learned how to find a solution by using substitution As an example i will find the solution to 5x-3y=27 and 2x+y=2 the first step is to use one of the equations and isolate one of the variable… Continue Reading →

This week we learned how to tell if two lines will be parallel, coincidence or have one intercept point. parallel: you will know if two lines are parallel by looking at there slope, if they are the same the line … Continue Reading →

This week we learned 3 different ways to write equations of linear relations General form ax+by+c+0 general form is usually considered useless because it does not give slope and X and Y are on the same side of the equation… Continue Reading →

how to find the length of an oblique line To find the length of an oblique line you have to use the Pythagorean theorem. to do this the formula is a^2 + b^2 = c^2 A= horizontal line of triangle… Continue Reading →

This week we learned about slope. to find slope you use the formula rise over run rise = y1-y2 run=x1-x2 So if you had two points on a graph ex (8,6) (2,3) you would subtract y1 by y2 over x1… Continue Reading →

This week we learned about function notation. Function notation looks something like this: F(x)= 6x-9 Function notation is another way of showing the value of y in a function because F(X)= Y So if F(6) Then our equation would be… Continue Reading →

Functions A function is a type of relation where each input has only one output example X Y 3 6 4 8 2 9 This is a function because every input has only one… Continue Reading →

Factoring “ugly trinomials” This method is for when the sum of the 2nd term and the product of the 3rd arent made with the same factors. Ex 2x^2 + 7x + 6 look at the factors of the first and… Continue Reading →
