Answer:
3p + 8n, 12p + 2n, 9p+4n, 6p+6n
8 columns bar graph.
Step-by-step explanation:
$2 = pen
$3 = notebook
This could be written as a bar graph in multiples of $6.00 along y axes.
3 pens + 8 notebooks. Then 12 pens + 2 notebooks.
Then 9 pens + 4 notebooks . Then 6 pens + 6 notebooks
3p + 8n, 12p + 2n, 9p+4n, 6p + 6n
3p = $6
8n = $24
12p = $24
2n = $6
9p = $18
4n = $12
6p = $12
6n = $18
and so on...
I hope this helps for question a=16

Answer:
This equation has 2 solutions.
1. 
2. 
Just look for the coordinates left ones are along x axis and right are on y axis
Answer:
-1/6
Step-by-step explanation:
To find the slope we use
m = (y2-y1)/(x2-x1)
= (-4-8)/( 1-3)
= -12/-2
=6
We want a line perpendicular, so we need the negative reciprocal
- (1/6)
-1/6
