What’s the unit rate on a graph that has three points that is 120:2, 180:3, and 240:4
To find the unit rate on a graph, we need to find the ratio of the y-coordinates to the x-coordinates of two points on the graph.
Using the given points:
Point 1: (120, 2)
Point 2: (180, 3)
Point 3: (240, 4)
To find the unit rate, we can compare the change in the y-coordinates to the change in the x-coordinates.
For Point 1 to Point 2:
Change in y = 3 - 2 = 1
Change in x = 180 - 120 = 60
The ratio of the changes is 1:60 or 1/60.
For Point 2 to Point 3:
Change in y = 4 - 3 = 1
Change in x = 240 - 180 = 60
The ratio of the changes is 1:60 or 1/60.
Therefore, the unit rate on this graph is 1/60.
