- substitution
Task goals
- Draw straight-line graphs supplied in y=mx+c form using a table of values.
- Draw straight-line graphs by plotting the y-intercept and stepping with the gradient as rise over run.
- Choose denominator-sized runs for fractional gradients so plotted coordinates remain exact.
- Interpret decimal gradients as equivalent fractions and draw horizontal equations y=c.
- Verify a finished line with a third point found by substitution.
Where this fits
What leads into this objective, and where it goes next.
Before
Finding x- and y-intercepts
Sketching a Straight Line from Its Equation
Forming equations of given straight line graph (using y=mx+c)
You are here
Drawing straight-line from given equation
Know
In the equation of a line y = mx + c, m and c represent constants (they are unchanging), y and x can vary, and all the values of x and y that satisfy the equation create an infinite number of points that form the line.
