Plotting coordinates focuses on how to place points accurately by moving along x first and then along y. In this lesson, focus on straight-line graphs connect coordinates, rates and equations.
Straight-line graphs connect coordinates, rates and equations. Gradient measures vertical change per horizontal step; the y-intercept records the value when x is zero. For plotting coordinates, the final written answer should make that exact relationship visible rather than hiding it inside an unexplained result.
Plotting coordinates: Straight-line graphs connect coordinates, rates and equations. Substitute one plotted coordinate into the equation or count a second rise-and-run triangle. Keep the plotting coordinates representation visible until the final line.
Plot draggable points on a coordinate plane, draw the line and compare its rise, run and axis crossing. Use the model to explain one change you notice while working on plotting coordinates.
Substitute one plotted coordinate into the equation or count a second rise-and-run triangle. Write that check beside the final plotting coordinates answer.
Plot (3, 2): move right 3 and up 2.

Given information: Plotting coordinates — A point is 3 right and 2 up from the origin. Write its coordinate. Method choice: use the plotting coordinates method and show each step with the stated values. Calculation or reasoning: Read horizontal first, then vertical: (3, 2). Final answer: (3, 2). Check: substitute or compare with the original information to confirm the result fits the question.
Given information: Plotting coordinates — A point is 3 right and 14 up from the origin. Write its coordinate. Method choice: use the plotting coordinates method and show each step with the stated values. Calculation or reasoning: Read horizontal first, then vertical: (3, 14). Final answer: (3, 14). Check: substitute or compare with the original information to confirm the result fits the question.
Check: Plot and label the point precisely.
Given information: Plotting coordinates — A point is 3 right and 13 up from the origin. Write its coordinate. Method choice: use the plotting coordinates method and show each step with the stated values. Calculation or reasoning: Read horizontal first, then vertical: (3, 13). Final answer: (3, 13). Check: substitute or compare with the original information to confirm the result fits the question.
Try explaining why each step works before checking the answer.

Think of plotting coordinates as a careful model: make the important values visible, change one thing at a time, and use the check to prove the answer fits.
Start by naming the given information and the exact result required for plotting coordinates.
Label and read both axes.
