Question

What is the y-intercept, b, of the additive relationship represented by this table?

Enter your answer as an integer in the box.

b =
x y
1 4
3 6

Answer 1

b = 3

Explanation:

Answer 2

• b = 3

Explanation:

Use the table to find the slope and y-intercept

Find the slope:

• m = (6 - 4)/(3 - 1) = 2/2 = 1

Find b using the pair (1, 4):

• 4 = 1*1 + b
• b = 4 - 1
• b = 3

The line is:

• y = x + 3

The y-intercept is 3
