: Make a scatter plot of the data set. Sketch a line of best fit, and give the equation of the line.
x 2 4 8 14 16 22 24 26
y 18 24 16 16 18 14 8 4
I see from graphing the points that the line moves in a neg. direction. That's as
far as I can figure. Please help.This question is from textbook saxon algebra 2
Once you have sketched your line, pick two points on your line and determine the coordinates of the two points, and . 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.
Next, use the two-point form of the equation of a straight line to develop your equation:
Do all of the indicated arithmetic and then you can either solve for y to give the slope-intercept form:
