Question

Help please!

1.What is the y intercept of the function?
2.What is the first difference?
3.Write an equation to represent the function given in the table. Remember we write linear functions in y=mx+b form!

Answer 1

1.What is the y intercept of the function?

y-coordinate when x = 0, take from the table.

• (0, 5)

2.What is the first difference?

Difference of y-values. This is the slope

• 7-5 = 2

3.Write an equation to represent the function given in the table

Use the first difference and the y-intercept: b = 5, m = 2

• y = 2x + 5
