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 .
Answer:
50% for pen
80% for homework
30% for both
(I don't know how they got 30% for both because it should be 40%.)
I need to know what the questions are to answer this.
X - 3y =2
2x + y= 11 | *3
x - 3 y = 2
6x + 3y = 33
-----------------
7x = 35
x= 35:7
x=5
2x+y=11
2*5 + y = 11
10 + y = 11
y= 11 -10
y= 1
