1/6 times 6 equals 1, the total value of the coat. Multiply 9 by 6 to get the total value: $54
Well, you need to find it in y=mx+b format.
the point you have is (-2, 1)
Y - 2 = -2/5(x - 5)......distribute thru the parenthesis
y - 2 = -2/5x + 2....add 2 to both sides
y = -2/5x + 2 + 2
y = -2/5x + 4 <== slope intercept form
First you multiply both sides by -4.
(y + 12) * (-4)
___________ = 5 (-4)
-4
then you should simplify.
y + 12 = -20
subtract 12 from both sides to isolate the y.
y + 12 - 12 = -20 -12
-20 minus 12 is -32.
y = -32.
