Algebra It’ not about the maths It’s about the English! Actually we are learning a new language… Algebra!
Algebra y = mx + c We are going to be exploring this equation this week to understand what it means.
Algebra y = mx + c By the end of the week you should : Understand what the y, m, x and c stand for Be able to plot a straight line graph using this equation Be able to read values for x and y off the graph you plot.
Algebra We are going to start by taking the equation y = x+1. If we replace x with a 3 then we know what y will be. y =x 3 y = 4 +1
x 0123 y=x+1y Algebra We replace x with several numbers and work out what y is each time. We put these in a table. 123 4
x 0123 y=x+1y Algebra We can add a new row to the table for a new equation, now lets add a row for y=x+2 and fill in the blanks 1234 x 0123 y=x+1y y=x+2y 2345
The final task is to plot the x and y points on a graph 1 0 3 2 4 5 6 7 8 1432 y x x 0123 y=x+1y 123 4 x x x x
Algebra You have four tables of equations. Your task this lesson is to: 1.Work out the missing values of y for each equation 2.Plot the line for each equation 3.Identify how m and c affect the line!
