2x + y = 4 can also be written y = -2x + 4. There are many methods to graphing linear equations. Here is my favorite: because there is only one variable (x) raised to the first power (x1 even though we don't often write it this way), we know that the graph is a straight line. So we need only find two points that lie on the graph and draw the straight line that runs through (and beyond) them.So plug in two different values for x and see what y= at these values. For instance, when x = 0, y = -2(0) + 4 = 4. So plot the point (0, 4) on your two-dimensional coordinate plane.Another x value: when x = 1. Plug that into the equation y = -2(1) + 4 = 2. So the point (1, 2) should be on the graph. A straight line through these two points gives you the graph of the equation.*Another method is to find just one point on the graph, say (0, 4) as we did above, then use the slope (the m in y = mx + b form) to direct the rest of the line. Our slope is -2, so every time x increases by one (move one notch to the right), your y value will be two units less than the previous y value.
A minor diagonal matrix is one where the only non-zero entries are along the diagonal that runs from bottom most left to upper most right.
It is 26.68 yards, approx.
The y-axis always runs vertically.
Domain is the set of all possible numbers for a function on the X axis on a graph, and range is the set of all possible numbers for a function along the Y axis on a grpah. (The X axis is the one that runs horizontally, while the Y axis runs vertically). The domain and range define from and up to which numbers a function's point (coordinate) may be located on a graph. To state the domain of a function, you must find out what values "x" may and may not be in the function (equation), and the same goes for range. A good way to check if you've got your domain and range right is to try plugging in the numbers that you have found to be "restricted" and see if they really do produce an impossible or inaccurate result, or doesn't give you a result at all!
The one that runs left to right, you mean..
On a standard Cartesian graph, there are two axes. The Y axis runs vertically, bottom to top and the X axis runs horizontally from left to right.
5. if there is a line that says for instance y= 5x the answer on how to graph it would be the slope is the fraction. How far it "rises" on the graph, over how far it "runs" goes to the right or left. ( the answer is 5/1 or it rises 5 spaces on the graph and it goes to the right one) If a slope is negative it goes to the left. Also if it was y= 5x +3 it would do the same thing as before, but instead of starting from the origin (0,0) it would start at +3 and go from there.
y-axis
A vertical line is a line that runs up and down. On a graph, it is either the y axis or parallel to the y axis. It is also perpendicular to the x axis.
The horizontal scale is called the x-axis. It represents the independent variable in a graph or table, and it runs from left to right. It helps to show the relationship between the data points being plotted.
The horizontal axis runs left to right because it is horizontal. The vertical axis runs up and down. In math, 'y' is associated with the horizontal axis and 'x' is associated with the vertical axis.

Latitude lines are the ones which are parallel to each other, with 0º being the Equator Longitude are the ones which radiate out from the poles and which get wider as they approach the Equator. 0º runs through Greenwich, near London.
A diagonal line that runs upwards and to the right.
The sagittal plane runs longitudinally and divides the body into right and left halves.
