The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...

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 ...

In this case both the slope and the y intercept are known and the equation can be written ... In this case two sets of coordinates are known but the slope is not known. This case involves the use of ...

You express a point slope form equation as y – y 1 = m (x – x 1), where m represents the slope of the line, and (x 1, y 1) are the coordinates of the given point through which the line passes.
