WEEK 13 – point slope form
This week in math 10 we learned about point slope form. Usually to find the slope formula you use the equation of
m= y1-y2/x1-x2 BUT to find point slope form you switch/move the equation to
m(x1-x2) = y1-y2
a good way to remember what you’re doing in point-slope form is to remember to ‘plug + play’.
That basically means to plug in the numbers into the equation and let algebra take over! Easy!
WEEK 12- slope formula
This week in math 10, we learned about slope formula. Slope formula is equal to
change y/change x
and that is equal to
Example: (3,7) and (-2,11)
Also keep in mind that 5/-4 would be equal to -4/5 , it all depends on how you do your equation
This week in math 10 we learned about graphing! First things first it’s important to understand what a variable is and that there are two types of variables, discrete and continuous. Variables are basically when the data or clues are given to us and it’s our job to find out where they go on a graph to showcase it a different way.
A discrete variable basically means a whole number / a number that you cannot divide. In other words, they don’t have an infinite number of values.A good example to remember this is how many people are in your household? As you cannot divide people in half (I would not like to see it anyway!), it counts as a discrete variable! Or maybe, how many cars sold from a dealership per month. As you cannot sell a fraction of a car, it counts as a discrete variable! When you’re graphing the dots and using a discrete variable, the dots on the graphs are not connected because the space between dots does not have value and there is nothing that is in between the dots on the graph as it cannot be divided.
A continuous variable meansthat there’s, in theory, an infinite number of possibilities. This variable is used to measure things like time, distance, weight, etc.The reason that they qualify as continuous is becausethey are not whole numbers. When you’re graphing the dots and using a continuous variable, the dots on the graphs are connected because the space between dots also has value.
This week in math 10 we learned about functions and relations!
This week in math 10 we learned about how to evaluate a notation function. First things first, we need to know the different parts of the function. You can see in the photo below that every part has a label and as this chapter is mostly vocabulary based, it’s important you know what someone could be referencing.
