[size=150]In this activity you are presented with linear equations in two variables of the form [b][color=#0000ff]a[/color][i]x[/i] + [color=#ff7700]b[/color][i]y[/i] = [color=#dd7e6b]c[/color][/b][/size][size=150][br]You will find the values of y corresponding to the given x values in the table.[br]The three pairs of x and y values form the x, y coordinates of three points. [br]Plot the points onto the graph by dragging them to the correct position.[br][br]See how the three points form a straight line. [br][br][/size][size=150]In fact, all the points on the straight line will have y-coordinate values which correspond to the calculated y values when the respective x-coordinates are substituted into the equation.[/size]
