Answer:
First find the gradient (m).
Pick any two points on x axis and their corresponding points on y axis in this format (x,y). point 1 (10,5) and point 2 (20,10) Gradient = (y2-y1) /(x2-x1) = (10-5)/(20-10) =5/10 Gradient (m)=1/2 Now that you know gradient, solve using either of the points you picked as shown below: Note pick a third in letters not numbers example point 3 (x,y)
Lets use point 1 (10,5) and point 3 (x,y). Gradient = (y-5)/(x-10) : Note we already know gradient is 1/2 so, 1/2 = (y-5) / (x-10) Rearranging and simplifying: y-5 = (1/2)(x-10) y-5=(1/2 x) - 5 Add 5 to both sides y-5+5=(1/2x)-5+5 y=1/2x+0 Final answer y=1/2x or y=0.5x
