Question 148183
y = 5 -4x 

(5, ____) (1, ____) (-1, ____) 

5, 1, and -1 represent x values. To find out their corresponding y values, simply plug in the value for x into the equation and solve for y. 


1. Start with {{{y = 5 -4x}}}. 

Plug in 5 {{{y=5-4(5)}}}. 

Simplify {{{y=5-20}}}. 

Solve {{{y=-15}}}. So when x=5, y=-15. (5,-15) 



2. Start with {{{y = 5 -4x}}}. 

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

Simplify {{{y=5-4}}}

Solve {{{y=1}}}. So when x=1, y=1. (1,1) 



3. Start with {{{y = 5 -4x}}}. 

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

Simplify  {{{y=5--20}}}

Solve {{{y=25}}}. So when x=-1, y=25. (-1,25)



Solutions: (5,-15) (1,1) (-1,25)
