First, find the slope of the line thru these 2 pts:

         5-4
m = --------- = -1/2
         2 -4 

Use the slope-intercept formula y = mx + b:

5 = (-1/2)(2) + b.  Then the y-intercept is 5 + 1, or 6:  y = (-1/2)x + 6

Multiplying this entire result (3 terms) by 2 results in 2y = -x + 12, or

x + 2y = 12 (answer)

Someone plzzz help I’m lost :(

Answer:

j = (h-4) / k

Step-by-step explanation:

Unless there is more information given about this question somewhere else in the assignment, I'm assuming you are being asked to solve this equation for j.

If so, then its just a matter of rearranging the equation so that it is in the form

j = (expression containing other variables)

(h-4) / j = k   (multiply both sides by j)

(h-4) = jk  (divide both sides by k)

j = (h-4) / k

Determine whether the variation between the indicated quantities is direct or inverse. The number of calories in a cheese pizza
-BARSIC- [3]

Answer:

The variance is direct.

Step-by-step explanation:

Since size of the pizza determines the amount of calories.

Let us say that a 2" x4" strip of pizza has 250 calories.

Then a pizza of twice the size (or 4" x 4") will have twice as many calories (500 calories) .
