Question

If the function f(x)= 3/2x-10 were graphed, which of the following would be true? A. All the y-values would be negative. B. As the x-values increase, the y-values would increase. C. All the x-values would be negative. D. As the x-values increase, the y-values would decrease.

Answer 1

Df/dx=3/2=1.5  so this line has a positive constant rate of change.  y increases by 1.5 for every 1 increase in x.

So B. is the only true statement as y values increase as x values increase.
