Question

How do you isolate 2x-y+8=0?

Answer 1

X would equal -4 and for the point on a graph would be -4,0

Answer 2

The best way to find the angular and linear coefficient is by assembling the reduced equation:
 
2x - y + 8 = 0
- y = - 2x - 8 .(- 1)
y = 2x + 8
 
The angular coefficient is the value that accompanies the X and the coefficient is the value that comes alone.
 
Angular Coefficient: 2
Linear Coefficient: 8
 
If you want to find the values ​​X and Y, we have:

2x - y + 8 = 0 
2(x - 8) = y 
x - 8 = 2 
x = 2+8 
x = 10 

2x - y + 8 = 0 
2*10 - y + 8 = 0
20 - y = - 8
- y = - 8 - 20
- y = - 28 .(-1)
y = 28

Confirm that the solution is correct:
2x - y + 8 = 0 
2*(10) - 28 + 8 = 0
20 - 28 = -8
- 8 = - 8 (TRUE)





I hope I have helped!
