using
the
the
graph

of the equation 2x- y + 3 = 0
find the value of y when x=-2​

Answer 1

Answer:

I dont have nb but i explain u how to do this

Step-by-step explanation:

2x-y+3

2(2)-y+3 =0

4-y+3=0

1+y=0

Y=0-1

Y=-1

Answer 2

Step-by-step explanation:

2x - y + 3 = 0

y = 2x + 3 -eq1

x =-2 -eq2

Substituting equation 2 in equation 1.

y = 2×-2 + 3

y = -4 + 3

y = -1

Substituting value of y in equation 1.

1×-1 = 2x + 3

-1 = 2x + 3

2x = -4

x = -2

Thus, plotting values of x and y respectively.
