Slope or gradient taken from any point of the graph are the same. Therefore, let’s take the points (0,5) and (1,3) to find its gradient.
gradient =(y2-y1)/(x2-x1) =(3-5)/(1-0) =-2
Now, let’s put in the value of the gradient and one of the y values and one of the x values in the equation y=mx+c to find the value of c. y=mx+c 5=-2(0)+c c=5
