Question

Draw the graph of each of the equation y-x=2. find from the graph (1) the value of y when x=4 . (2) the value of x when y=-3​

Answer 1

hey here is your answer

Answer 2

Answer:

(1) The value of y = 6.

(2) The value of x = -5.

Step-by-step explanation:

Consider the given equation as follows:

y - x = 2 _____ (1)

Substitute the value $0$ for x in the equation $(1)$ as follows:

y - 0 = 2

y = 2

Substitute the value $0$ for y in the equation $(1)$ as follows:

0 - x = 2

x = -2

The two points of the functions are listed in the table as follows:

x      0       -2

y      2        0

Now, the plot these points on to the graph.

(1) From the graph,

The value of y is 6 when x = 4.

or,

For x = 4,

y - 4 = 2

y = 2 + 4

y = 6

(2) From the graph,

The value of x is -5 when y = -3.

or,

For y = -3,

-3 - x = 2

-x = 2 + 3

x = -5
