Linear Function y=mx+b: Increase and decrease in relation to slope

Choose the correct answer

If the slope is negative then the is decreasing

Which of the following is true?

_{^{If the slope is positive, then the function is increasing.}}

Choose the correct answer

_{^{If the slope is zero, then the function is constant.}}

The graph of the linear function passes through the points $B(4,7),A(7,2)$

Decreasing function

The graph of the linear function passes through the points $B(0,0),A(4,6)$

Bottom-up function

The graph of the linear function passes through the points $B(5\frac{1}{2},10),A(\frac{1}{2},5)$

Bottom-up function

The graph of the linear function passes through the points $B(1,5),A(7,1)$

Decreasing function

Given these two points of a linear function:

$B(0,0),A(2,0)$

How can we identify the function?

Constant function
