Question

Which two points are on the graph of y = -x + 3?

A. (-1, -2), (1, 4)
B. (1, 2), (0, -3)
C. (0, 3), (4, -1)
D. (4, -1), (1, 3)

Answer 1

The graph is already in slope-intercept form. So what you do it take the slope and the y intercept. The slope would be 1/-1. So since you know the slope and the y-intercept you can graph the graph. So the y-intercept is where the graph crosses over the y-axis. So here the y-intercept is 3. So start at 3 and go to the right one point then down one point and repeat that. Then to go the opposite way of the graph toward negative infinity you would do the opposite of the slope. which would be -1/1. So you go to the right one then up on. DO that until you real the limit of you graph. All that is left is to look at the graph and find which points lie on the line of the graph.

Is that better?? -_-
