Question 388330: Graph the inequality on a plane.
4x+5y≤20
Please tell me what are the paired orders and tell me what paired order goes where. If I am looking at the graph....does the first paired order go in the north east south east north west or south west and please explain the same way for the second paired coordinates. This will help me understand how to graph better. Thank you in advance!

Question 388332: Find an equation for the line with the given properties. Express the answer using the general form of the equation of a line.
Perpendicular to the line -4x + 5y = -23; containing the point (-3, 7)
-3x - 5y = -23
-4x - 5 = -4
-5x + 4y = -13
-5x - 4y = -13

Question 388348: 1 Use the discriminant to determine whether the quadratic equation has two unequal real solutions, a repeated real solution, or no real solution without solving the equation.
5x2 - 2x - 1 = 0
repeated real solution
two unequal real solutions
no real solution
2 Write the general form of the equation of the circle with radius r and center (h, k).
r = 2; (h, k) = (4, -4)
x2 + y2 + 8x - 8y + 20 = 0
x2 + y2 + 8x + 8y + 20 = 0
x2 + y2 - 8x - 8y + 20 = 0
x2 + y2 - 8x + 8y + 20 = 0
3 Write the standard form of the equation of the circle with radius r and center (h, k).
r = 10; (h, k) = (4, -10)
(x + 4)2 + (y - 10)2 = 100
(x + 4)2 + (y - 10)2 = 10
(x - 4)2 + (y + 10)2 = 100
(x - 4)2 + (y + 10)2 = 10

Question 388386: Okay, not sure if I did these problems right or not.. my algebra book isn't very clear with the process.
1. Determine the slope and y-intercept of the graph: 3x + y = 8
I got slope = 3, y-intercept = 8? right or wrong? if so please explain
2. Determine the slope and y-intercept of the graph: -x + 2y =4.
I got slope = -1/2, y-intercept = 2? same as above
Thank You Everyone who helps me here! xoxo

Question 388361: Translate the sentence into a mathematical equation. Be sure to identify the meaning of all symbols.
1 The profit derived from the sale of x video cameras is $420 per unit less the sum of $2700 costs plus $120 per unit.
If P is profit and x the units sold, then P = 420x + 2700 - 120x or
If P is profit and x the units sold, then P = 420x - (2700 + 120x) or
If P is profit and x the units sold, then P = - (2700 + ) or
If P is profit and x the units sold, then P = 420x - (2700 - 120x) or
2Find the center (h, k) and radius r of the circle.
