Hi can you guys pls help me am doing hw and I don't seem to understand it

In order to be a linear function, the graph of the function has to be a straight line. y=mx+b is the formula for slope-intercept form, specifically linear equations. The correct answer to this problem would be B, Harriet is correct. The equation y=11x could be considered a linear function, as long as the y intercept, or b in the equation, is equal to zero.

Let me know if this helps you make sense of the problem at all, or if I should try to explain it again in a different way.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
