Question

Draw the graph for the equation x-y=4​

Answer 1

Answer:

First, solve for two points which solve the equation and plot these points:

First Point: For

x

=

0

0

−

y

=

4

−

y

=

4

−

1

⋅

−

y

=

−

1

⋅

4

y

=

−

4

or

(

0

,

−

4

)

Second Point: For

y

=

0

x

+

0

=

4

x

=

4

or

(

4

,

0

)

We can next plot the two points on the coordinate plane:

graph{(x^2+(y+4)^2-0.035)((x-4)^2+y^2-0.035)=0 [-10, 10, -7, 3]}

Now, we can draw a straight line through the two points to graph the line:

graph{(x - y - 4)(x^2+(y+4)^2-0.035)((x-4)^2+y^2-0.035)=0 [-10, 10, -7, 3]}

Answer 2

Step-by-step explanation:

x-y=4

x-4=y

put X as 2. put X as 3. put X as 4. put X as -2

y=x-4. y=x-4. y= x-4. y= x-4

y=2-4. y= 3-4. y= 4-4. y= -2-4

y= -2. y= -1. y= 0. y= -6
