Transcript of y = mx + c year11
y = mx + c
Learning Objective:- to plot straight line graphs (grade C) and use y = mx + c (grade B)to find
parallel lines (grade A)
Tracking A
Key words: gradient, y intercept, parallel
Challenge:Which pair of lines are parallel and how do you know?Which pair are perpendicular and how do you know?
Success Criteria
Grade D recognise parallel and perpendicular lines
Grade C plot straight lines from a table of values
Grade B use y = mx + c to plot straight lines
Grade A use y = mx + x to find parallel lines
Grade A* use y = mx + c to find perpendicular lines
Using your mini whiteboards...
... Fill in this table
x -1 0 1 2 3
y
y = 2x + 1
Can you plot this line?
Use your mini whiteboards and the tables of values to plot
these lines...y = 3x + 2
y = -2x + 1
y = 4x + 2
y = 3x - 1
y = mx + cWhat is the gradient and y intercept for
each of these lines?
y = 3x + 2
y = -2x + 1
y = 4x + 2
y = 3x - 1
Success Criteria
Grade D recognise parallel and perpendicular lines
Grade C plot straight lines from a table of values
Grade B use y = mx + c to plot straight lines
Grade A use y = mx + x to find parallel lines
Grade A* use y = mx + c to find perpendicular lines
