Question

Graph the line with slope -1 that contains (2, -2)

Answer 1

at best ... plot the given point

define the slope y/x as a fraction: -1/1

use the fraction to define how to move to the next point, y = -1, x = 1, so move down by 1, and to the right by 1 .. plot that point.

draw a line that passes thru the 2 points ... or continue to make more points if wanted.
