Exercise 57 Page 162

To complete the table, we should calculate corresponding values of y for the different values of x. To do that, we have to substitute the value of x into the equation y=x- 34 and simplify.

y=x-3/4

Substitute

x= - 2

y= - 2-3/4

NumberToFrac

a = 4* a/4

y=-8/4-3/4

MoveNegFracToNum

Put minus sign in numerator

y=-8/4-3/4

SubFrac

Subtract fractions

y=-11/4

MoveNegNumToFrac

Put minus sign in front of fraction

y=-11/4

If we do this for the rest of the values of x, we can complete the table.

x	- 2	- 1	0	1	2
Substitution	-2-3/4	-1-3/4	0-3/4	1-3/4	2-3/4
Write as Fraction	-8/4-3/4	-4/4-3/4	0-3/4	4/4-3/4	8/4-3/4
y=x-3/4	-11/4	-7/4	- 3/4	1/4	5/4
