Isolate y on the left side:
- Move 4x to the right side
- Then divide the entire equation by 5
This gives you:
y = -
x - 3
This gives you the equation in the familiar (y = ax + b) format. Graph this by finding your intercepts.
- Crosses the y-axis when you put 0 in for x --> y = -3
- Crosses the x-axis when you put 0 in for y --> x = -
Then just draw your straight line through both points.
