Question

How do you solve Scatter Plots ? I'm so lost. Help!

Answer 1

Once you have sketched your line, pick two points on your line and determine the coordinates of the two points, \[(x_1,y_1)\] and \[(x_2,y)\] . If your sketched line passes through one or two of the scatter plot points, that makes it easy. Otherwise, you will just have to eye-ball it.

Answer 2

Next, use the two-point form of the equation of a straight line to develop your equation:

Answer 3

Thank you! :)

Answer 4

Do all of the indicated arithmetic and then you can either solve for y to give the slope-intercept form:

Answer 5

or arrange it into standard form:
