In week 15 in math 10 we learned how to find the slops of a graph. the slope in this is 2/4 because it rises by 2 and runs by 4. And this slope is a positive slope because its going up. If you do not have an exact rise and run you look for the “nice points” and use those to direct you to find your rise and run.
In week 14 of math 10 we learned how to tell the difference between a function or a relation just by looking at a graph, mapping diagram or a table chart.
graphing: If there are dots that have the filled in circle that are found vertically on the sae x value then that is a relation, if there are two lines found vertically above each other than that is a relation as well.
mapping diagram: If your X values are the same then that is a relation, if they are all different that is a function, the only way for X to have the same values as each other is if the Y values are the same for both.
table chart: If your X values are the same then that is a relation, if they are all different that is a function, the only way for X to have the same values as each other is if the Y values are the same for both.
In week 13 in math 10 we learned how to tell the difference between a relation and a function and what they are, we learner what and input and output were, what a independent and dependant variable is, we learned how they are graphed and 5 ways to express them which can be by a table of value, ordered pairs, graphing, an equation and a mapping graph.
Independent, input, x and range all mean the same thing.
Dependant, output, y and domain all mean the same thing.
Relation- numbers that have common multiple, numbers may varie in similarity.
Function- numbers that have no common multiples and they are singular meaning no number will be the same.
