Question

Which is a correct way of graphing the line y = –x – 2?

A) Plot a point at (0, –2). Use the slope of 1 to plot another point. Draw a line through the points.

B) Plot a point at (–1, 0). Use the slope of –2 to plot another point. Draw a line through the points.

C) Plot a point at (–1, 0). Use the slope of 2 to plot another point. Draw a line through the points.

D) Plot a point at (0, –2). Use the slope of –1 to plot another point. Draw a line through the points

Answer 1

y = -x - 2.....in y = mx + b form, the m represents the slope and the b represents the y int. (and if u didnt already know, -x is the same as -1x)

so in ur equation, the slope is -1 and the y intercept is -2....or (0,-2)

so u would plot (0,-2) and use the slope of -1 to plot another point. Draw a line through the points.
