You can put this solution on YOUR website! 5x + 4y = 16
4y = -5x +16
y = -5/4x +4
.
This equation in slope-intercept format. Both x and y can vary from -infinity to +infinity.
slope = -5/4
y-intercept = 4, which defines the point (0,4)
.
Another good point to find is the x-intercept, which the point where y=0.
.
0 = -5/4x +4
5/4x = 4
5x = 16
x = 16/5
x = 3 1/5
.
If x=16/5, y=0: (16/5,0)
.
With two points, you can draw a line.
