Given the equation
2x + 3y = 8
The given equation represents a line
It is required at minimum two points to graph the line
So, assume two value for x and find y using the given equation
When x = -2
2 * -2 + 3y = 8
-4 + 3y = 8
3y = 8 + 4
3y = 12
y = 12/3 = 4
so, the point (-2 , 4) lie on the line
And assume x = 4
so, 2 * 4 + 3y = 8
8 + 3y = 8
3y = 0
y = 0
So, the point (4 , 0) lie on the line
so, the line is passing through the points (-2 , 4) and ( 4 , 0)
By connecting the points and extending the line we will get the graph of 2x + 3y = 8
