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

3

Explanation:

First step: Find the slope, Using the Formula y2 - y1 / x2 - x1 =

6-4=2 3-1=2 then u divde the y/x 2/2=1 So the slope is 1.

Step 2: Use the Slope- Intercept formula, Y=mx+b so 4 = 1(1)+b so 4 = 1 + b

Step 3: subtract 1 on both sides so 4-1=3 1-1=0 so 3 is the Y-Intercept.
