About This Lesson
<p>Teaching resource based on Coordinates & Straight-Line Graphs. Perfect for use with all types of interactive whiteboards. File is a spreadsheet and requires macros to be enabled. Read and plot positive (x; y) coordinates in the first quadrant. Read and plot positive and negative (x; y) coordinates in all four quadrants. Recognize straight-line graphs parallel to the x or y axes and main diagonals. Generate coordinates and plot straight-line graphs of the form y = mx + c. Find the gradient; y-axis intercept and equation of a straight-line graph</p>
one of the best!!
