One serving of beef contains 2 grams of fat and 11 grams of protein. Complete the double number line diagram to show the amounts of fat and protein in 1, 2, 3, and 4 servings of beef.

7x − y = 23

Step-by-step explanation:

The equation of line shown using the two points would be:

We know perpendicular line's slope (the number before x) would be "negative reciprocal of this, hence the equation of the perpendicular line would take the form:

Since it goes through (4,5), we can plug in 4 in x and 5 in y to figure out b:

So the equaiton is  y = 7x - 23

In standard form it is: 7x - y = 23
