L7Teacher's Notes Topic: Alg - y=mx+c
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).
What other lines pass through (0,20) ?
Straight lines
(a) On the graph, draw a different straight line with gradient 1
The graph shows a straight line with gradient 1
(b) The equation of another straight line is y = 5x + 20
The straight line y = 5x + 20 passes through ( 0, ____ )
(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?
