Answer:
Option A. The y-intercept of the line representing the relationship is 6
Step-by-step explanation:
Let
x ---> the number of jelly donuts
y ---> the number of chocolate donuts
step 1
Find the slope of the linear equation
take the points
(4,10) and (8,14)
The formula to calculate the slope between two points is equal to
substitute
step 2
Find the equation of the line in point slope form
we have
substitute
Convert to slope intercept form
isolate the variable y
therefore
The y-intercept of the line representing the relationship is 6
