x-y =4

5-y=4

-y=4-5

-y= -1

y=1

Answer 2

The value of y is 1.

Step-by-step explanation:

Consider the provided equation.

$x - y = 4$

Subtract x from both sides.

$x-x - y = 4-x$

$-y = 4-x$

Multiply both sides by -1.

$y = -4+x$

$y = x-4$

Now substitute x = 5

$y = 5-4$

$y = 1$

Hence, the value of y is 1.

To draw the graph of the function find another coordinate by substitute x=0.

$y = 0-4$

$y =-4$

Now join the coordinates (5,1) and (0,-4).
