Answer

Yes, it is a function. The equation of this function is $y = 2x + 3.$ The y-intercept is 3, and for every time x increases, y increases by $2$.

Work Step by Step

This is a linear function because it has a constant slope. The y-intercept is 3 and the slope is 2, so the equation is $y=2x+3$.
