Question

Which of the following is the correct equation for the trend line in the scatter plot?
A) y = -x + 5
B) y = 2/5x - 2
C) y = 5x + 5
D) y = 5x - 1

Answer 1

first get your slope which is \[ \frac{ rise }{ run }\]

slope or m = 5/1 or 5

next find where the line crosses the y-axis. This is your y-intercept

y-intercept or b = 5

now plug it into the equation y=mx+b

y = 5x+5
