The table below shows pairs of values for a linear function. X -2 -1 0 1 2 у 4 1 3 2 3 2 2 A different function is defined by the equation y = -2x. Which statement is true? O A. The y-intercept of both functions is 0. OB. Both functions have a negative slope. C. The functions are both proportional. D. Both functions have a positive slope.

Solution

From the table we can find the intercept looking for the value if x=0 and we got y= 3

Then we can find the slope like this:

[tex]m=\frac{2-3}{2-0}=-\frac{1}{2}[/tex]

And the equation would be:

y= -1/2 x +3

And then the best solution would be:

B. Both functions have a negative slope
