# In Exercises 33 to 36, find the value of the indicated variable for each given formula. Y ,  if  m = Y − y X − x , m = − 3 2 , y = 1 , X = 2  and  x = − 2

To determine

To find:

The value of the indicated variable Y for the given formula.

Explanation

Concept for evaluating the expression:

1) In an algebraic expression, letters can stand for numbers.

2) Substitute a specific value for each variable.

3) Then perform the operations.

Calculation:

Given:

Formula: m=Yâˆ’yXâˆ’x

Substitute m=âˆ’32,Â y=1,X=2Â andÂ x=âˆ’2 in the given formula, we get

m=Yâˆ’yXâˆ’xâˆ’32=Yâˆ’12âˆ’(âˆ’2)âˆ’32=<
