Find the equation of the line through point (−1,2) ( − 1 , 2 ) and perpendicular to +3=3 x + 3 y = 3 . Use a forward slash (i.e.
"/") for fractions (e.g. 1/2 for 12 1 2 ).

Answer:
y = x + 3
Step-by-step explanation:
I'm assuming that you are asking for a line perpendicular to
3x + 3y = 3 and going through (-1, 2)
first find the slope of the line
3y = -3x + 3
y = -1x + 1, the slope is -1 so the perpendicular slope is 1
y = mx + b
2 = 1(-1) + b
3 = b
y = x + 3

Answer:
Each Pencil Cost 4 Dollars
Step-by-step explanation:
First you can subtract 21 by 9 to get 12 dollars which shows how much he spent.
Second you can divide 12 by 3 to get 4 dollars spent. So he spent 4 dollars on each pencil.
