Which point represents the unit rate? a, b, c, or d

Point C

The unit rate is when the change in x is 1, so basically in this case the x coordinate is 1. That applies to point C. The answer is not point B as B is not on the diagonal line.

Unit rate = slope = rise/run = (change in y)/(change in x)

It has a slope of 1 nd a y intercept of -2

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept
