Answer:
11/5
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (5 - -6)/(-4 - -9)
= (5+6)/( -4+9)
= 11/5
Answer:
16
Step-by-step explanation:
<em>x = markers</em>
<em>y = colored pencils</em>
12x = y
x= 72
y = 6
Okay, so what I did was divide 78 by 12 (to find the number of colored pencils) which gave me 6.5. You can't have half a colored pencil, so I rounded the number down to get 6. To find the number of markers, I multiplied 12 and 6 <em>(12x = 6) </em>which gave me 72. To check my answer I added the two amounts, 72 + 6, which gave me 78.

Use vertical pipes around the value.
Example:
abs(-4) = |-4| = 4
