Vectors give directions and can be three dimensional objects. Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. Write down all three forms of the equation of the line.

It is important to not come away from this section with the idea that vector functions only graph out lines. Now we need an equation for x in terms of t. Writing an Equation Given the Slope and Y-Intercept Write the equation for a line that has a slope of -2 and y-intercept of 5.

Real World Problems When you have a real world problem, there are two things that you want to look for!

We know that the new line must be parallel to the line given by the parametric equations in the problem statement.

Note that any one of the constants can be made equal to 1 by dividing the equation through by that constant. Graph the line segment using your equations. It can be anywhere, a position vector, on the line or off the line, it just needs to be parallel to the line.

In this problem we are asked to do the following: Well, we can substitute t in for x. Each value of t gives a different point on the line. The blue point on the graph has approximately the following coordinates: Due to the nature of the mathematics on this site it is best views in landscape mode.

Once we have one form we can easily get any of the other forms from it using simple algebraic manipulations.

We will assume that the graph has x and y axes and a linear scale. Write an equation in slope intercept form given the slope and y-intercept.

We need to recall that the point-slope form looks like the following: And t ranges from 0 to In many applications, we think of x and y "varying with time t" or the angle of rotation that some line makes from an initial location. We know a point on the line and just need a parallel vector.

We could just have easily gone the other way. In the first case where we are given two points, we can find m by using the formula: Since these two points are on the line the vector between them will also lie on the line and will hence be parallel to the line.

The best way to get an idea of what a vector function is and what its graph looks like is to look at an example. Calculate the slope from the y-intercept to the second point.

The rate is your slope in the problem. The following are examples of a rate: How do we write an equation for a real world problem in slope intercept form?May 27, · write an equation in slope-intercept form of the line with parametric equations: x=2+3t and y=4+t Thank you!!Status: Resolved.

The calculator will find the equation of the parallel/perpendicular line to the given line, passing through the given point, with steps shown.

For dra Parametric Equations; Solving of Equation with Two Variables; Enter the equation of a line in any form: y=2x+5, x-3y+7=0, etc. Write all suggestions in comments below. Show steps.

About. Finding the Equation of a Line Given Two Points – Notes Page 2 of 4 Step 3: Write the answer. Using the slope of 3 and the y-intercept of 1, the answer is: y = 3x + 1. To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope.

This is the value of m in the equation. Next, find the coordinates of the y -intercept--this should be of the form (0, b). Write an equation in slope-intercept form of the line with parametric equations: x=2+3t and y=4+t Step 1. The slope-intercept form is given as y=mx+b with m as the. Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information.

All you need to know is the slope (rate) and the y-intercept. Continue reading for a couple of examples!
