Mathematical Statement Analysis: Evaluating Truth Values in Given Expressions

Question

Which of the following is true?

Video Solution

Step-by-Step Solution

To solve this problem, we'll examine the statements related to the slope of a linear function and determine which are true:

  • A linear function is described mathematically by the equation y=mx+b y = mx + b , where m m is the slope and b b is the y-intercept.

  • The slope m m determines the direction of the line:

    • If m > 0 , the line is increasing as x x increases.

    • If m=0 m = 0 , the line is horizontal, meaning it is constant.

    • If m < 0 , the line is decreasing as x x increases.

Now, let's match these characteristics to the provided choices:

  • If the slope is positive, then the function is increasing.

    • This is true as per the description above; a positive slope means the function increases as x x increases.

  • If the slope is negative, then the function is constant.

    • This is incorrect; a negative slope results in a decreasing function.

  • If the slope is positive, then the function is decreasing.

    • This is incorrect; a positive slope corresponds to an increasing function.

  • If the slope is negative, then the function is increasing.

    • This is incorrect; a negative slope means the function is decreasing.

Therefore, the correct statement is that If the slope is positive, then the function is increasing.

Answer

If the slope is positive, then the function is increasing.
