Question 1057222
y = mx+b, where x and y are the coordinates (y goes up and down, x horizontally)
3x+4y = -16
4y = -3x-16
y = -3x/4-4
Choose 0 to substitute for x: 
y = -3(0)/4-4 
y = 0/4-4
y = 0-4
y = -4 We now have one set of points: (0, -4)
Now choose 1 to substitute for x:
y = (3(1)/4)-4
y = 3/4-4
y = 3/4+-(4/1*4/4) - multiply to get a common denominator 4
y = 3/4-16/4
y = (3-16)/4
y = -13/4 now we have another set of points: (1,-13/4)
Try substituting 2 for x and you'll get a third set of points: (2,-5/2)
Now you have three ordered pairs you can graph:
(0, -4), (1, -13/4), (2, -5/2)
This is what you get:
