Finding the missing coordinate-
a line goes through the point (6,-2) and has a slope of
-3.
what is the value of a if the point (2.7) lies on the line? a=

Step-by-step explanation:

The correct question is

What is the value of a, if the point (a,7) lies on the line?

step 1

Find the equation of the line in point slope form

we have

substitute

----> equation in point slope form

step 2

Find the value of a

we know that

If a ordered pair lie on the line, then the ordered pair must satisfy the equation of the line

we have

(a,7)

substitute in the equation of the line

Solve for a

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
