The graph is the set of all value of x that are less than or equal to 3, so you draw a line parallel to the number line, under the 3 and to the left of it (less than). Also, underneath the point three you draw a circle at the end o your line. Since it is less than or equal to you fill in that circle. Otherwise it would only be an outline circle.

The set of negative integers.
To graph this in Cartesian coordinates start by solving the inequality for either x or y: y --less than or equal to-- 3-x/3 Now, if this were not an equality we would have y=3-x/3 this equation would yield a linear graph with a slope of -1/3 and a y intercept of 3 But the graph for the inequality must also could include all of the points (x,y) below this line so we end up with not a line but an entire region. so right now in your head picture the line y=3-x/3. now color in the region below the line. this is the region where y is less than 3- x/3 and the line its self accounts for y=3-x/3.
It is a graph of isolated points - nothing more, nothing less!
times it
to graph in equaltities in two variables, you graph the two numbers and/or variables. then you look at the sign to see if its greater than, less than, greater than or equal to, or less than or equal to and you graph the line as dashed or a solid
I think you would use an average two step equation to solve. Graph on a number line. If it was -2, go over 2 to the left, and make a dot. It is hollow or solid. It is solid if there is a line beneath the less than or greater than sign indicating that it is equal to....
ya motherrrrrrrrrrr.
FALSE
Equations are statements that state two expressions are equal, while inequalities are statements that state two expressions are not equal, meaning one is greater or less than the other. The graph of the solution set of an equation is a line or a curve, while the graph of the solution set of an inequality is a region at one side of the boundary line or curve obtained by supposing that the inequality was an equation.
I will guess that what you refer to as a "shadow graph" serves as a way to visually represent all the answers, or solutions, to a linear inequality. For instance, if you graph y=x (a linear equality), you get the diagonal line through the origin heading 45 degrees up and to the right in one direction and down and to the left in the other. Any point on that line is a solution, even extended beyond the visible graph in both directions, "forever". However, if you graph y
The graph is the set of all value of x that are less than or equal to 3, so you draw a line parallel to the number line, under the 3 and to the left of it (less than). Also, underneath the point three you draw a circle at the end o your line. Since it is less than or equal to you fill in that circle. Otherwise it would only be an outline circle.

it will be an infinite region bounded by the lines x=2 and x=6

x2-2x = 15 x2-2x-15 = 0 (x-5)(x+3) = 0 Therefore: x = 5 or x = -3
