# How to write an equation with a slope of 0

We say that the variable y varies directly as x. In the ordered pair x, yx is called the first component and y is called the second component. The x-coordinate of the point where a line crosses the x-axis is called the x-intercept of the line, and the y-coordinate of the point where a line crosses the y-axis is called they-intercept of the line.

For right now, we are only focusing on slope. Play with different values of b and observe the result. Graphing a Positive Slope Start with the point 0, The b variable is the y intercept - the point where the line crosses the y axis. Solution We designate 3, 5 as x2, y2 and -4, 2 as x1, y1.

In our problem, that would have to be 2. If we denote any other point on the line as P x, y See Figure 7. Draw a straight line through your points.

Move both sliders and observe the overall effects of these two coefficients a and b working together. It only takes a minute and any amount would be greatly appreciated. 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.

We can get down to business and answer our question of what are the slope and y-intercept. The ratio of the vertical change to the horizontal change is called the slope of the line containing the points P1 and P2. That is, a, b is a solution of the inequality if the inequality is a true statement after we substitute a for x and b for y.

The graphs of any two solutions of an equation in two variables can be used to obtain the graph of the equation. In general, if two lines have slopes and m2: Since the line passes through the origin, we must choose another point not on the line as our test point.

The line gets steeper as the absolute value of the slope get larger. This example is written in function notation, but is still linear. In general let us say we know a line passes through a point P1 x1, y1 and has slope m.

The denominator is 1, so we went right 1 4.The y y y y-intercept of the line is (0, 3) (0,\greenE{3}) Write the equation of the line. Explain.

Problem 2. Write the equation of the line. Explain. Writing equations from any two points.

The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

This is described by the following equation: =. (The Greek letter delta, Δ, is commonly used in. After completing this tutorial, you should be able to: Find the slope given a graph, two points or an equation.

Write the equation of a line parallel or perpendicular to a given line. If we know the equation of a line, we can use what we know about slope to write the equation of a line that is either parallel or perpendicular to the given line.
