Step 1:I'll solve this step by step using the given data points and the slope-intercept formula y = mx + b.
Step 2:: Identify the data points
- Point 2: $$(4, 5)
From the graph, I can see the following points:
Step 3:: Calculate the slope (m)
m = \frac{5 - 3}{4 - 2} = \frac{2}{2} = 1
Step 4:: Use point-slope form to find the y-intercept (b)
b = 1
3 = 1(2) + b
Step 5:: Write the equation of the line of best fit
y = 1x + 1
Final Answer
y = x + 1
