The gradient and intercept of a line can easily be stated by looking carefully at its equation.
For the line with equation y = mx + c, the gradient is m and the intercept on
the y-axis is c.
m is the coefficient of x when in the form y = ......
c is the number on its own
Draw the line which is represented by y = 2x + 1
Comparing y = 2x + 1 to y = mx + c, we see that m = 2 and c = 1
The gradient of the line, m, is 2 and the intercept, c, is 1.
This means that it crosses the y-axis at (0, 1) and from this point we move 1 to the right and 2 up to draw the line (or 4 to the right and 8 up)
The line is shown below.
