Math Problem Statement

Write the linear equation that gives the rule for this table: x: 3, 4, 5, 6 y: 47, 48, 49, 50

Solution

The table provided asks for the linear equation in the form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept. Let's analyze the table to extract the dataThe table provided asks for the linear equation in the form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept. Let's analyze the table to extract the

Step 1: Find the slope (mm)

The slope (mm) is calculated using the formula: m=y2y1x2x1m = \frac{{y_2 - y_1}}{{x_2 - x_1}} We can take any two points from the table to find the slope. Using the points (3,47)(3, 47) and (4,48)(4, 48):

m=484743=11=1m = \frac{{48 - 47}}{{4 - 3}} = \frac{1}{1} = 1

Step 2: Find the y-intercept (bb)

To find bb, we use the equation y=mx+by = mx + b with one of the points, say (3,47)(3, 47): 47=1(3)+b47 = 1(3) + b 47=3+b47 = 3 + b b=473=44b = 47 - 3 = 44

Final Equation:

The linear equation is: y=x+44y = x + 44
