Find Linear Equation from Table

What is the equation for the table?

• y =1/4x -3

• y =4x - 3

• y = -3x -3 

• y =-2x -3 

What is the function of the table?

• y=3x+1

• y=4x-2

• y=x+1

• y=x+7

What is the equation of the linear function?

• y = -3x + 10

• y = -3x + 16

• y = 3x + 10

• y = 3x + 16

Write the Equation!

• y = -5/2x - 2

• y = 5/2x - 1

• y = 2/5x - 3

• y = 5/2x - 3

Writing Equations:
Given the following table, write the linear equation.

• y = 9x + 3

• y = 3x + 12

• y = 3x + 9

• y = 1x + 12

How do you find slope from a table?

• put the entire table int a list and spreadsheet nd go to menu, statistics, one variable statistics

• pick two points and subtract the x values from the y values

• pick two points and put them in lists and spreadsheets. then go to menu, statistics, stat calculations, linear regression

• divide each value in the y column by a value in the x column and find the average of the answers.
