Lesson Outline – Linear Equations
Lesson Outline - Linear Equations
Aim: to understand all aspects of straight line graphs
Lesson Objective: to be able to plot straight line graphs for given equations (by using table of values)
Prior Vocabulary: x-axis, y-axis, co-ordinates, table of values, x-value, y-value
New Vocabulary: intercept, x-intercept, y-intercept, equation of a line
Possible misconceptions: all graphs go upwards from left to right,
all graphs are in the +ve x/ +ve y quadrant, all graphs are straight,
all graphs start at/go through (0,0), straight line graphs are finite
Key Questions: What do you already know about straight line graphs?
If I tell you the value of x, how will you work out what the value of y is?
