Just mulitiply the original price and times it by 172 do the same thing for both.
Y=-3x+2:
Already in slope intercept form
Graph by plotting a point on (0,2)
Then move 3 points up and 1 to the right and plot the point and keep doing that a couple times
-3x-y=-2:
Add -3x on both sides
The result would be
-y=3x-2
Divide everything by negative 1
Y=-3x+2
Both equations are the same so they are the same line
7 pounds = 122 ounces so $6.72 divided by 122 is .55 cents I hope I’m right
