About What is slope-intercept form?

Writing an equation in slope intercept form from a graph

Solve Find the slope. Check Check your result by using the coordinates of the other point. You can use a linear equation to make predictions about values that are beyond the range of the data. This process is called linear extrapolation.

Problem-SolvingTip Determine Reasonable Answers Deciding whether an answer is reasonable is useful when an exact answer is not neccessary. Write an equation of the line that passes through the given point and has the given slope. Write an equation in slope-intercept form to find the total cost C for p people.

How much would it cost for 15 people? He starts the timer when the car is 5 feet away. After 2 seconds the car is 35 feet away.

Slope-Intercept Form

Write a linear equation to find the distance d of the car from Greg. Estimate the distance the car has traveled after 10 seconds. ZOOS Refer to the beginning of the lesson. Write a linear equation to find the attendance in millions y after x years. Let x be the number of years since Write a linear equation to find the cost C of a dictionary y years after If this trend continues, what will the cost of a dictionary be in ?

SparkNotes: Writing Equations: Slope-Intercept Form

B Write an equation of the line that passes through the given point and has the given slope. DOGS Inthere were about Inthe number was Estimate the number of golden retrievers that will be registered in Write an equation that represents the total cost of the membership. How many aerobics classes did she take?

What is the cost of each archived article for which you pay a fee?The slope-intercept is the most “popular” form of a straight line.

Many students find this useful because of its simplicity. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y-intercept can easily be identified or read off from this form. And by using countless examples, together we will learn how to identify the slope (m) and y-intercept (b) from an equation, write an equation in slope-intercept form, graph a line using the slope and y-intercept, and how to change an equation from slope intercept to standard form.

Slope intercept form is used when your linear equation is written in the form: y = mx + b. x and y are your variables. m will be a numeral, which is your slope.

In this form only (when your equation is written as y = .) the coefficient of x is the slope and the constant is the y intercept.

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.

Graph this line by using its slope and y-intercept.. The equation is already given to us in slope-intercept form.

writing an equation in slope intercept form from a graph

We can tell at a glance that the y-intercept is -2 and the slope kaja-net.com can also tell that you've been working out lately. Linear Equations.

A linear equation is an equation for a straight line. These are all linear equations: There are many ways of writing linear equations, but they usually have constants The most common form is the slope-intercept equation of a straight line: Slope (or Gradient) Y Intercept.
