Teacher's Notes Topic: Alg - y=mx+c Straight lines The graph shows a straight line with gradient 1 (a) On the graph, draw a different straight line with gradient 1 L7 Draw a different straight line ... and another, and another ... Find an unusual one (eg it crosses the y-axis at 3.7, or it has a gradient of 1 but on this diagram it doesn't cross either axis). (b) The equation of another straight line is y = 5x + 20 The straight line y = 5x + 20 passes through ( 0, ____ ) What other lines pass through (0,20) ? (c) A straight line is parallel to the line with equation y = 5x + 20 It passes through the point ( 0, 10 ) What is the equation of this straight line? What other questions can you ask/answer?
