# Week 16 – Math 10

This week in math 10, we were focused on solving problem application of systems such as number, money, mixtures, distance, and speed. Therefore, today I am going to show you how to solve money problems. Example 1. Four pencils and two erasers cost \$3 .50. At the same prices, two pencils and five erasers cost…

# Week 15 – Math 10

This week in math 10, we learned solving systems of linear equations. We can solve systems by Graphing, Substitution and Elimination. So, I am going to show you how to solve systems by Elimination that is my favourite method. In the elimination method you either add or subtract the equations to get an equation in…

# Math 10 – Week 14

This week in math 10, we started unit 9 and learned about system of equations. A system of equations is a collection of two or more equations with a same set of unknowns. Example: two equations that share the variables x and y x + y = 6 2x + y =8 Those two equations are…

# Math 10 – Week 13

This week in math 10, we learned about how to do Point-Slope Form. The point-slope form is  y − y1 = m(x − x1) Example: Slope “m” = 5/2.5 = 2 We know m, and also know that (x1, y1) = (6,6), and so we have y-6 = 2(x-6) We can simplify it: y-6 = 2(x-6) = y-6…

# Week 12 – Math 10

This week, we learned about Slope and how to find it. Slope is     Rise changes to y, and Run changes to x.   Example.  Find the slope of the line that passes through A (3,2) and B (6,4). y1 = 2, y2 = 4, x1= 3, x2 = 6. You can find the…

# Week 11 – Math 10

This week in math 10, we learned about characteristics of linear relations. If you know the location of two points ( A and B ) like here, You could get the distance between them. 1. Make a right angled triangle. 2. Using the Pythagoras c² = a² + b², you can get the distance of c.
