Facts Concerning Slope m of Linear Functions

[nycmath]

Facts

A. When the slope m of a linear function is positive (m > 0), the line slants upward from left to right.

B. When the slope m of a linear function is negative (m < 0), the line slants downward from left to right.

C. When the slope m of a linear function is zero (m = 0), the line is horizontal.

Give an example for A, B, and C by creating three linear functions. Then graph each linear function on the xy-plane.
