Question 111321
equation:

{{{y = 4 - 5x}}}

the domain is: {{{-2}}},{{{ -1}}}, {{{1}}}, {{{3}}}, {{{4}}}

a) 

{{{y = 4 - 5x}}}...........plug in {{{x = -2}}}

{{{y = 4 - 5(-2)}}}

{{{y = 4 + 10}}}

{{{y = 14}}}

b)

{{{y = 4 - 5x}}}...........plug in {{{x = -1}}}

{{{y = 4 - 5(-1)}}}

{{{y = 4 + 5}}}

{{{y = 9}}}

c)

{{{y = 4 - 5x}}}...........plug in {{{x = 1}}}

{{{y = 4 - 5(1)}}}

{{{y = 4 - 5}}}

{{{y = -1}}}

d)

{{{y = 4 - 5x}}}...........plug in {{{x = 3}}}

{{{y = 4 - 5(3)}}}

{{{y = 4 - 15}}}

{{{y = -11}}}

e)

{{{y = 4 - 5x}}}...........plug in {{{x = 4}}}

{{{y = 4 - 5(4)}}}

{{{y = 4 - 20}}}

{{{y = -16}}}
