Question

The line of best fit for a scatter plot is shown: A scatter plot and line of best fit are shown. Data points are located at 0 and 1, 2 and 1, 2 and 3, 4 and 3, 4 and 5, 6 and 3, 7 and 5, 9 and 4. A line of best fit passes through the y-axis at 1 and through the point 4 and 3. What is the equation of this line of best fit in slope-intercept form?

Answer 1

y = (1/2)x +1

Step-by-step explanation:

Given the two points on the line are (0, 1) and (4, 3), the line's equation can be written using the two-point form:

y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

y = (3-1)/(4-0)·(x -0) +1 . . . . use the given point values

y = (1/2)x +1

Explanation:

Answer 2

y = (1/2)x +1

Explanation:

Given the two points on the line are (0, 1) and (4, 3), the line's equation can be written using the two-point form:

y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

y = (3-1)/(4-0)·(x -0) +1 . . . . use the given point values

y = (1/2)x +1
