Get your head around plotting points, drawing grid lines, and understanding basic vocabulary like intercept, coordinates, etc.
This will make working with transformations on a grid easier.
When questions involve vectors or reflections across lines like y = -3 you need to be confident working with coordinates.
Coordinates - Lets start with the basics!
Level 1 - Plotting small integer coordinates in the first quadrant
Level 2 - Plotting small integer coordinates in all four quadrants
Level 3 - Plotting larger integer coordinates in the first quadrant
Level 4 - Plotting larger integer coordinates in all four quadrants
Level 5 - Plotting decimal coordinates in all four quadrants
Coordinates Picture - Plot points to produce a picture.
Which Transformation? - This is an easy exercise to begin with asking you to recognise some very simple transfomations.
Level 1 - Reflect a shape in a given line
Level 2 - Translate a shape by a given vector
Level 3 - Rotate a shape about a given point by a given angle
Level 4 - Enlarge a shape from a given point by a given scale factor
Level 5 - Transform a shape by a given matrix
Level 6 - Mixed questions without diagrams
Level 7 - Describe the transformation from the diagrams

Look at different options then select the best size for your practice.
General form for a straight line equation y=mx+c
y is the dependent variable.
x is the independent variable.
m is the slope of the line.
c is the y-intercept, the point where the line crosses the y-axis.
For the equation y=2x+3
Y-intercept (c) = 3 (start at the point (0,3)).
Slope (m) = 2 (move 1 unit to the right and 2 units up to find another point, like (1,5)).
Draw a straight line through these points.
Put your cursor on these points on the graph

(0 , 0)
(1 , 1)
(-2 , -2)
(4 , 4)
