# Write an equation in standard form for the line described thus

Now looking at this vector visually, do you see how we can use the slope of the line of the vector from the initial point to the terminal point to get the direction of the vector? Here is all this visually. We can move the x term to the left side by adding 2x to both sides. We have seen that we can transform slope-intercept form equations into standard form equations. But why should we want to do this? There are a number of reasons. First, standard form allows us to write the equations for vertical lines, which is not possible in slope-intercept form.

Remember that vertical lines have an undefined slope which is why we can not write them in slope-intercept form. This example demonstrates why we ask for the leading coefficient of x to be "non-negative" instead of asking for it to be "positive". For horizontal lines, that coefficient of x must be zero. This topic will not be covered until later in the course so we do not need standard form at this point. However it will become quite useful later. A third reason to use standard form is that it simplifies finding parallel and perpendicular lines.

Let us look at the typical parallel line problem. The usual approach to this problem is to find the slope of the given line and then to use that slope along with the given point in the point-slope form for a linear equation.

Any line parallel to the given line must have that same slope. Of course, the only values affecting the slope are A and B from the original standard form.Write an equation in slope -intercept form for the line described. slope , passes through (0, 5) The y-intercept of the equation LV Thus, Ms.

Cooper ¶s daily salary is \$ Write an equation in slope -intercept form for. The Standard Form of the equation of a line looks like: Ax + By = C [ note: the slope is (-A/B) ] First, convert the given equation into Standard Form.

@Aditya: Thanks! Yes, it took me a while to really see the equation, there may be a nicer way to go back and streamline how it was presented — I’d like to avoid the need for people to have multiple readings:). Dec 13,  · Learn how to write the equation of a line that is parallel to a given line.

the slope-intercept form, the standard form, etc. Thus given the equation of a line and a point through which. Introduction. This manual is the basic textbook for anyone writing an ASTM standard. A study of Parts A, B, C, or E will show the proper form for the principal types of standards including a detailed explanation of how to write each section, from the title to the appendixes. Within Parts A, B, C, and E, the first section lists the preferred sequence of headings and indicates whether these.

(Recall that the flux of physical quantities described by the diffusion equation is proportional to the gradient; thus a zero gradient means no flux.) With no flux added to the region, the final potential at all points in the region is simply the average of the initial condition.
