There are 3 steps to find the Equation of the Straight Line :1. Find the slope of the line 2. Put the slope and one point into the "Point-Slope Formula" 3. SimplifyStep 1: Find the Slope (or Gradient) from 2 PointsWhat is the slope (or gradient) of this line?
A straight line always has the same slope at whatever point it is measured. To show that in the expression y = mx + c, m is the gradient, we begin with a couple of examples as in Figure 2.1(b) and (c) In Figure 2.1(b), we have the graph of y = 2x + 3. Take any two ...

Point-slope form: y – y1= m(x – x1). Given: x1= 4, y1= -2, and m = 3 Plug in the values: y – (-2) = 3(x – 4). Simplify: y + 2 = 3x – 12. Examples with Solutions Example 1 Consider the equation y = 3x for a straight line. To draw its line, we must fir...
For example, we recall that if we know the 𝑦-intercept, 𝑏, of the line, and its slope, 𝑚, then we can write the equation of the line in the slope–intercept form: 𝑦=𝑚𝑥+𝑏. However, this form for the equation of a straight line assumes that we know both the ...
The gradient, m, of the line joining (x_1,y_1) to (x,y) is given bym= (y-y_1)(x-x_1)⇒ y-y_1=m(x-x_1)This is a very useful form of the equation of a straight line. Two positions of the point (x_1,y_1) lead to particularly important forms of the equation. ...
So far we have seen that a straight line can be described as a line with a constant gradient and we know how to find the gradient of any particular line from a graph of the line. In this section we shall look more closely at the co-ordinates of points on a straight line to see ...
