You need the Least Common Multiple of 12 and 9.
That's 36.
3 x 12 = 36
4 x 9 = 36
The answer is A) <span>Increasing: x < 7; decreasing: x > 7</span>
Slope = (change in 'y') / (change in 'x')
If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.
The slope of the line is 3 .
If there was a chart with this that would be helpful but at this time with the information you have given you can not solve this problem
