  • You draw the graph of the straight line x + 2y = 5.
  • Evaluate the inequality at the origin: 0 + 2*0 > 5 or 0>5. This is not true so the part of the plane NOT containing the origin (above and to the right of the line) is the valid region.
  • Also, since it is a strict equality, the line itself is not part of the valid region.

Can you tell me how to graph -2x equals 2y plus 5?

-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5


How do you graph the equation negative x plus 2y equals 4?

if 2y-x=4, than y=1/2*x+2 we can now see that the graph is linear with slope 1/2 and goes through point (0,2)


What does 6x plus 2y equals 8 look like on a graph?

The picture of the graph is in the related links section.


How do you graph the equation 8x plus 2y equals -1?

Same way you graph y = -4x - 0.5


What is the effect on the graph of the equation 4x plus 2y equals 12 is changed to 36?

I guess you mean 4x + 2y = 12 is changed to 4x + 2y = 36. The graph is translated (shifted) up the 7 axis by 24.


What is the graph of the equation 2x2-6x plus 2y plus 18 equals 0?

2x2-6x+2y+18 = 0. Subtract the 2y from both sides. 2x2-6x+18 = -2y. Divide all by -2 to get y by itself. -x2+3x-9 = y. This graph is going to be a parabola that opens downward, like a frown.


Describes the graph of the equations 2y equals 3x plus 2 and 4y equals 6x plus 1?

The lines are parallel.


What is the y-intercept of the graph of 4x plus 2y equals 12?

4x+2y = 12 2y = -4x+12 y = -2x+6 So the y intercept is 6 and the slope is -2


2Y equals X plus 4 in a graph?

2y = x + 4Divide each side by 2:y = (1/2)x + 2The graph is a straight line with a slope of (1/2) and a y-intercept of 2.
