Find the slope of a line without a graph by knowing 2 points the line goes through. e.g. A line passes through the points (2 , 5) and (5 , 17). What is the slope of the line?

Know the formula y = mx + b and understand that m = slope and b = y-intercept. Work out the slope and y-intercept from the equation of a line without the graph. e.g. What is the slope and y-intercept of the line y = 4x+2?

Know the formula y = mx + b and understand that m = slope and b = y-intercept. Match graphs of straight lines to their equations. e.g. If you have 3 straight line graphs drawn, match them to y = 2x+1, y+x = 4, y = -3x-5
