Question

if x is equal to 4 and Y is equal to minus 2 a solution of the linear equation 2 X + 4 Y is equal to zero​

Answer 1

If X is 4 and y is -2 then

2×4 +4 ×-2 = 0

8+-8=0

Answer 2

Answer:

Step-by-step explanation:

Explanation:

To express this equation in the form of

y

=

m

x

+

b

you need to subtract #color(green)(2x) from each side of the equation:

2

x

−

2

x

+

y

=

2

x

+

y

=

−

y

=

−

x

+

8

This equation is now in the slope intercept form.

The slope-intercept form of a linear equation is:

y

=

m

x

+

b

Where

m

is the slope and

b

is the y-intercept value.

Looking at our equation:

y

=

−

2

x

+

8

Therefore:

m

=

−

2

so the slope is

−

2

b

=

8

so the y-intercept is

8

or (

0

,

8
