# Write a equation in standard form line given two points In the third year there were 57 participants. We will substitute 5 for x x is the year and solve for y. This will help us to figure out when he will have saved up enough to buy the MP3 player. Let's quickly review the steps for writing an equation given two points: 1. Write the equation using the slope and y-intercept. We want to find what the value of x is when y equals Now you will have to read through the problem and determine which information gives you two points.

## How to write an equation in standard form given one point and slope

So we just need to set y equal to in our equation, and solve for x. Now that we have an equation, we can use this equation to determine how many participants are predicted for the 5th year. Therefore, our two points are 1,35 and 3,57 Let's enter this information into our chart. This will help us to figure out when he will have saved up enough to buy the MP3 player. We want to find what the value of x is when y equals We will substitute 5 for x x is the year and solve for y. In the third year there were 57 participants. Andre wants to buy an MP3 player. This can be written as 1,35 In the third year, there were 57 participants. Okay, now what? Write an equation that can be used to predict the amount of participants, y, for any given year, x. Ok, now let's apply this skill to solve real world problems. Find the slope using the slope formula. We can use that to figure out how long it will take him to save all the money he needs to buy the MP3 player. Based on your equation, how many participants are predicted for the fifth year?

This can be written as 3,
