# SET BC video project

This is our SET BC project about the salmon population in the Coquitlam river, and how it is rapidly decreasing because of some of our everyday actions. During the course of this project we had to collaborate, and share ideas, by using our knowledge and research that we have found through out the time we […]

# Math 9 enlargements and reductions

Here is my original table showing the coordinates of my shape. Next, we were asked to enlarge the shape by 3, Lastly, we were asked to reduce the number by 0.5 based off of our original table. Here is my final desmos shape, (with all of the enlargements, and reductions, I did an extra one, as well […]

# What I Have Learned About GR9 Linear Inequalities

Linear Inequalities Solving: what do these signs mean? (≥, ≤, >, <) These signs represent the larger number(s) in the linear inequality, so if there is a 3x<5. this inequality would represent that 5 is larger than the 3x, another example is x≥5 this inequality represents that the x is more than or equal to […]

# Linear equations

Question #1 add negative 3x and remove the zero pairs add -2 and remove the zero pairs add -1x to each side remove the zero pairs the next step would be to divide into the x in this case x= 4 question #2 add +5 to each side remove zero pairs add +6 to […]

# What I have learned about GR.9 linear relations AND graphing

Vocab: X-axis- the x axis is the horizontal line on a graph (shown with this chart) Y-axis- the y axis is the vertical line on a graph (also shown with this chart) […]

# Wonder Project

The question I researched for the wonder project was ”Should we be able to change the DNA of our unborn children” Studies have shown that if you really wanted you could design your baby, their hair colour up to their intelligence and their personality. You can choose to remove all possible chances of your child […]
