$4 for 20 donut holes; $7 for 40 donut holes

Step-by-step explanation:

The question is

Find out the linear equation between the cost in dollar and the number of donuts holes

Let

x -----> the number of donuts holes

y ----> the cost in dollars

we have the ordered pairs

(20,4) and (40,7)

Find the slope m

The formula to calculate the slope between two points is equal to

substitute the values

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

substitute

Find the equation of the line in slope intercept form

Isolate the variable y

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

x = 12

y = 1

for the points!
