Find the equation that represents the proportional relationship between in this graph

y = 2x

First, we need to find a point on the graph that the line goes through. (1, 2) is an example we can use because the line goes through the point (1, 2). Now, we need to see how high the point (1, 2) is from the X axis. (1, 2) is 2 units away from the X axis. Now, we need to find out how far it is from the Y axis. (1, 2) is 1 unit away from the Y axis. Now, the formula for slope is Distance of Y/ Distance of X. So, we just plug in our values to get 2/1, or 2. We know that the slope - intercept formula is y = mx + b. M is the slope, B is the Y intercept. Since there is no Y intercept, we can put 0 for Y intercept. Slope is 2, so formula is Y = 2x.
