• 9 units up

• 5 units down, 1 unit left

• 9 units down

• 5 units down, 1 unit right

• 5 units up, 1 unit left

• 1 unit up, 5 units right

Answer explanation

DON'T SKIP THIS!

You would have normally plotted 5 units up, 1 unit right, but there was no room to make a point that way. Therefore, you had to immediately go in the opposite directions of 5 down & 1 left.

Perform the correct steps until you have plotted all possible visible points. If correct, the graph of both equations should match the picture shown.

• 9 units up

• 5 units down, 1 unit left

• 9 units down

• 5 units down, 1 unit right

• 5 units up, 1 unit left

• 1 unit up, 5 units right

Answer explanation

DON'T SKIP THIS!

You would have normally plotted 5 units up, 1 unit right, but there was no room to make a point that way. Therefore, you had to immediately go in the opposite directions of 5 down & 1 left.

Perform the correct steps until you have plotted all possible visible points. If correct, the graph of both equations should match the picture shown.

• 2 units up, 5 units right

• 6 units up

• 2 units down, 5 units right

• 5 units down, 2 units right

• 5 units up, 2 units right

• 6 units down

Answer explanation

DON'T SKIP THIS!

Perform the correct steps until you have plotted all possible visible points. (The final graph will be shown after the next equation.)

Which statement best describe how to graph this line.
y=\frac{2}{3}x\ +4

• Start at the y-intercept of 4 which is (0 , 4) then slope the line by moving up 2 right 3. Then do the slope over and over. 

• Start at the origin (0,0) then slope the line by moving 2 over 3. Then do the slope over and over. 

• Start at the y-intercept of 4 which is (4, 0) then slope the line by moving up 2 left 3. Then do the slope over and over. 

• Start at the y-intercept of 4 which is (0 , 4) then slope the line by moving down 2 over 3. Then do the slope over and over.

Consider the line y=-3x+8. AFTER you plot the y-intercept, how would you use your slope to plot your next point?

• From the y-intercept, go down 3 and right 1.

• From the y-intercept, go down 3 and left 1.

• From the y-intercept, go left 3 and up 1.

• From the y-intercept, go left 3 and down 1.

In the equation y=mx+b, what does the m represent?
