Now we have these two points and remember that this is a linear equation because notice, in this equation here, it only has a degree of 1. All I have to do is plot these two points and then draw a ...

The straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\), the gradient of the line, by forming a right-angled triangle using the ...

Example Find the equation of the line that goes through the points (−1, 3) and (3, 11). Sketch the two points and join them with a straight line.
