Open the slope applet. Move point B around the Cartesian plane with your mouse.

(a) Move B to the point whose coordinates are ( 2, 7). What is the slope of the line?

(b) Move B to the point whose coordinates are ( 3, 6). What is the slope of the line?

(c) Move B to the point whose coordinates are (4, 5). What is the slope of the line?

(d) Move B to the point whose coordinates are (4, 4). What is the slope of the line?

(e) Move B to the point whose coordinates are (4, 1). What is the slope of the line?

(f) Move B to the point whose coordinates are (3, -2). What is the slope of the line?

(g) Slowly move B to a point whose x-coordinate is 1. What happens to the value of the slope as the x-coordinate approaches 1?

(h) What can be said about a line whose slope is positive? What can be said about a line whose slope is negative? What can be said about a line whose slope is 0?

(i) Consider the results of parts (a)–(c). What can be said about the steepness of a line with positive slope as its slope increases?

( j) Move B to the point whose coordinates are (3, 5). What is the slope of the line? Move B to the point whose coordinates are (5, 6). What is the slope of the line? Move B to the point whose coordinates are (-1, 3). What is the slope of the line?
