Question

2. Write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. Show all your work, including the points used to determine the slope and how the equation was determined.

Answer 1

Answer:

y=x

Step-by-step explanation:

By using the (y2-y1)/(x2-x1), you can find y=mx+b

Points: (30,30) and (60,60)

(60-30)/(60-30)= 30/30=1

Your m value (slope) is 1.

For the y-intercept, your value is 0

The full answer is y=x
