3x+4y+4=0
1. Set the equation equal to y so it is in y=mx+bformat.
4y=-3x-4
y=(-3/4)x-(4/4)
y=(-3/4)x-1
2. Start at (0,-1) make a point **b/c y-intercept(b) is -1**
3. Count down 3 and right 4 make another point. **b/c slope(m) is -3/4**
Hint:remember "rise over run", numerator of slope is amount up or down
(+ is up, - is down) and denominator is amount run left or right (+ is
right, - is left)
4.Take a ruler and draw a line between 2 points.
Using a graphing calculator: enter y=(-3/4)x-1 in y= and graph

Describes the graph of the equations 2y equals 3x plus 2 and 4y equals 6x plus 1?
The lines are parallel.
3x plus 2y equals 4 -3x plus 4y equals -10?
(2, -1)
Which is easier to graph 3x 4y equals 8 or y equals -0.75x plus 2?
They are the same equation just written differently so they are both easy to graph.
How do you graph 4y equals 8-3x?
Sensible but hard to explain
What would the graph look like for the line 3x plus 4y equals 8?
3x+4y = 8 4y = -3x+8 y = -3/4x+2 in slope intercrpt form It has a negative slope so the straight line goes 'downhill'

-5
How do you graph 4y equals 8-3x?
Sensible but hard to explain
What would the graph look like for the line 3x plus 4y equals 8?
3x+4y = 8 4y = -3x+8 y = -3/4x+2 in slope intercrpt form It has a negative slope so the straight line goes 'downhill'
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
The graph of 3x plus 4y-4 equals 0 crosses the line y equals -2 at what value of x?
3x + 4y - 4 = 0 y = -2 3x + 4(-2) - 4 = 0 3x - 8 - 4 = 0 3x = 12 x = 4 (4,-2)
Which is easier to graph 3x plus 4y equals 8 or y equals -0.75x plus 2?
Here they are in there slope intercept forms. y = -3/4x + 2 [3x+4y=8] y = -3/4x + 2 [y=-0.75x+2] Well look at that they are the same. How do you like that. So they much be equal easy to graph.
How do you rewrite -3X plus 4Y equals 11?
4y = 3x+11 or as y = 3/4x+11/4
Solve the system of equations 3x plus 4y equals 12 2x plus 4y equals 8?
x = 4 and y = 0
3x plus 2y equals 7 2x plus 4y equals 18?
(-1, 5)
