# Write an equation for a line

Less Office has equations that you can readily insert into your documents. We heard you loud and clear! Let's quickly review the steps for writing an equation given two points: Find the slope using the slope formula. Write the equation using the slope and y-intercept. Ok, now let's apply this skill to solve real world problems.

Now you will have to read through the problem and determine which information gives you two points. Remember a point is two numbers that are related in some way. Also remember, that when identifying a point from a word problem, "time" is always the x-coordinate.

In the first year, there were 35 participants.

## Add an equation to the equation gallery

In the third year there were 57 participants. Write an equation that can be used to predict the amount of participants, y, for any given year, x. Based on your equation, how many participants are predicted for the fifth year?

Identify your two points. This can be written as 1,35 In the third year, there were 57 participants. This can be written as 3, Therefore, our two points are 1,35 and 3,57 Let's enter this information into our chart.

Now that we have an equation, we can use this equation to determine how many participants are predicted for the 5th year.

All we need to do is substitute! We will substitute 5 for x x is the year and solve for y.GCSE (1 – 9) The Equation of a Line Name: _____ Instructions • Use black ink or ball-point pen.

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.. If you know two points that a line passes through, this page will show you how to find the equation of the line. In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula.

Anytime we need to get the equation of a line, we need two things. A line has a slope of 7 and goes through the point negative 4, negative What is the equation of this line in slope-intercept form? So the equation of any line in slope-intercept form is y is equal to mx plus b, where m is the slope and b is the y-intercept.
