We will assign a number to a line, which we call slope, that will give us a measure of the "steepness" or "direction" of the line. It is often convenient to use a special notation to distinguish between the rectan- gular coordinates of two different points.

We can designate one pair of coordinates by x1, y1 read "x sub one, y sub one"associated with a point P1, and a second pair of coordinates by x2, y2associated with a second point P2, as shown in Figure 7.

Note in Figure 7. The ratio of the vertical change to the horizontal change is called the slope of the line containing the points P1 and P2. This ratio is usually designated by m. Thus, Example 1 Find the slope of the line containing the two points with coordinates -4, 2 and 3, 5 as shown in the figure at the right.

Solution We designate 3, 5 as x2, y2 and -4, 2 as x1, y1. Substituting into Equation 1 yields Note that we get the same result if we subsitute -4 and 2 for x2 and y2 and 3 and 5 for x1 and y1 Lines with various slopes are shown in Figure 7.

Slopes of the lines that go up to the right are positive Figure 7. And note Figure 7. However, is undefined, so that a vertical line does not have a slope. In this case, These lines will never intersect and are called parallel lines.

Now consider the lines shown in Figure 7. In this case, These lines meet to form a right angle and are called perpendicular lines. In general, if two lines have slopes and m2: If we denote any other point on the line as P x, y See Figure 7. In general let us say we know a line passes through a point P1 x1, y1 and has slope m.

If we denote any other point on the line as P x, y see Figure 7. In Equation 2m, x1 and y1 are known and x and y are variables that represent the coordinates of any point on the line.

Thus, whenever we know the slope of a line and a point on the line, we can find the equation of the line by using Equation 2.

Section Solving Exponential Equations. Now that we’ve seen the definitions of exponential and logarithm functions we need to start thinking about how to solve equations involving them. Graph a system of two inequalities. Remember from the module on graphing that the graph of a single linear inequality splits the coordinate plane into two regions. On one side lie all the solutions . "Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.

Example 1 A line has slope -2 and passes through point 2, 4. Find the equation of the line. The slope and y-intercept can be obtained directly from an equation in this form. Example 2 If a line has the equation then the slope of the line must be -2 and the y-intercept must be 8.

Solution We first solve for y in terms of x by adding -2x to each member.Deterministic modeling process is presented in the context of linear programs (LP).

LP models are easy to solve computationally and have a wide range of applications in diverse fields.

GRAPHING LINEAR EQUATIONS MP1 Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution.

This site provides solution algorithms and the needed sensitivity analysis since the solution to a practical problem is not complete with the mere determination of the optimal solution.

The solution region for the previous example is called a "closed" or "bounded" solution, because there are lines on all sides. That is, the solution region is a bounded geometric figure (a triangle, in that case). Practice: Two-variable inequalities from their graphs.

Equations. Basic (Linear) High School Math Solutions. The solution of a linear system is the ordered pair that is a solution to all equations in the system. One way of solving a linear system is by graphing. The solution to the system will then be in the point in which the two equations intersect.
