6x + 7y = 3y - 3

Answer:

y = 2x/3 + 2/3

Step-by-step explanation:

1. Find the slope of the given line.

y = mx + b

6x + 7y = 3y -3

4y = -6x - 3

y = (-6x-3)/4 = -3x/2 - 3/4

The slope of y = -3/2

The slope of a line perpendicular to the line of 6x + 7y = 3y -3 would be the negative reciprocal of the slope so the slope of the line perpendicular would be -1/(-3/2) = 2/3

The equation would be:

y = 2x/3 + b

Since b is unknown, but a point is known, we plug in x and y values.

-8 = 2*(-13)/3 + b

Then solve for b:

b = 2/3

<h3>Answer:  2.4 pounds per dollar</h3>

Explanation:

We can set up the ratio

12 pounds : 5 dollars

Then divide both parts of that ratio by 5 so that the "5 dollars" becomes "1 dollar"

  • 12/5 = 2.4
  • 5/5 = 1

The ratio 12 pounds : 5 dollars is equivalent to 2.4 pounds : 1 dollar
