Graph the equation y = 2/3x - 4. Move the dots to represent the y-intercept and the next point after using the slope.

Answer explanation

You need three points. 1 at the y-axis, 1 left of the y-axis, & 1 right of the y-axis

Graph the line.

y = 2x + 2

Graph a line with a y-intercept of 1 and slope of 3.

• 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.
