# Write an equation through two given points

What is the equation of this line in slope-intercept form? So any line can be represented in slope-intercept form, is y is equal to mx plus b, where this m right over here, that is of the slope of the line. And this b over here, this is the y-intercept of the line. Also, a reminder that you might see something like this: From the coefficients of the equation, the mole ratio is 3: However, this reduces to a 1: That means that answer choice a would be considered by most teachers to be the correct answer.

Please note that using a 3: The same answer is obtained using 3: The ChemTeam, when in the classroom now retiredwould use the unreduced ratio in calculations done for teaching purposes. This is because, invariably, if the reduced ratio is used, the question would be asked: Given the balanced equation: The correct answer is b 1: When I saw this problem on Yahoo Answers, the first answer given was 2: Make sure to write the numbers of the ratio in the same order as used in the question.

The first substance mentioned goes in the numerator, the second mentioned in the denominator. What is the molar ratio between copper II sulfate and water in the following compound? Notice that this is not a chemical reaction, it is simply a chemical formula of a hydrate. Remember, hydrates have a fixed amount of water per mole of the non-water compound. In this example, the molar ratio is 1: For every one mole of CuSO4, there are five moles of water.

What is the molar ratio between the anhydrous compound and water for the following hydrates?The diffusion equation describes the diffusion of species or energy starting at an initial time, with an initial spatial distribution and progressing over time.

If we divide the final equation through by the product X(x)T(t), we obtain the following result. is will be the same as the solution to the problem with fixed temperature given.

Writing Linear Equations Given Slope and a Point. When you are given a real world problem that must be solved, you could be given numerous aspects of the equation.

If you are given slope and the y-intercept, then you have it made.

You have all the information you need, and you can create your graph or write an equation in slope intercept form very easily. This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.

(For a review of how this equation is used for graphing, look at slope and graphing.). I like slope-intercept form the best. A line has a slope of negative 3/4 and goes through the point 0 comma 8.

What is the equation of this line in slope-intercept form? So any line can be represented in slope-intercept form, is y is equal to mx plus b, where this m right over here, that is of the slope of the line.

This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.). I . Solve the equation.

The examples done in this lesson will be linear equations. Solutions will be shown, but may not be as detailed as you would like.
