    Okay, so for every other equation something is being raised to an expoenent, when something is being raised to an exponent this means that the line will be curved to a degree like this. |dw:1432948202275:dw|

    Which statement best explains whether y = 4x + 8 is a linear function or a nonlinear function? It is a linear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are on a straight line. It is a nonlinear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are not on a straight line. It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line. It is a nonlinear function because the graph contains the points (0, 8), (1, 12), (2, 16)

    Okay what is the slope in this case? and what is the y-intercept?

    remember y=mx+b m being the slope and b, being the y-intercept.

    No, here ill graph it so you can better understand it, the y-intercept is the b

    remember slope is rise over run, so you would start at positive 8 to graph this then go down 4 left 1 or up 4 right 1
