If the function f(x) = -1/2x - 7 were graphed, which of the following would be true? a. the y-values would be negative. b. as the x-values increase, the y-values would increase. c. the x-values would be negative. d. as the x-values increase, the y-values would decrease.

ANSWER

D. As the x-values increase, the y-values would decrease

EXPLANATION

The given function is


The slope of this function is


Since the slope is negative, there is a negative or an inverse relationship between x and y.

As the values of x increases, the values of y decreases.

Also, as the values of x decreases, the values of y increases.

The first option is not true because as x is becoming bigger and bigger negatively, y will become positive.

For instance, when



This implies that,



Options B is obviously not true because the function has a negative relationship between x and y.

Option C is also false because, x can be positive since it is the independent variable.

See graph

Therefore, the correct answer is option D.

Well in order to lose a pound you would have to burn 1,500 calories. the more calories you burn the more weight you lose. in order to lose 2 pounds you would have to run 4 hours and 28 minutes.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
