please follow me I am sure I will follow you back and give you a lot of thanks

Step-by-step explanation:

graph{y=-4x [-10, 10, -5, 5]}

Explanation:

To solve this equation, first move the

4

x

to the other side to make the

y

by itself. Do this by subtracting

4

x

from each side.

y

+

4

x

−

4

x

=

0

−

4

x

Simplify

y

=

−

4

x

Once you simplify, plug in random values for

x

(

1

,

2

,

,etc) and then the answer you get is your

y

value. You can use the graph for help.

Example:

x=2⇒y=−4(2)=-8 So x=2,y=−8
