Finding the Equation of a Trend Line
A graph titled Passing Statistics has pass attempts on the x-axis, and yards on the y-axis. A line goes through points (24, 127) and (36, 163).

The scatterplot and trend line show the correlation between the number of pass attempts a quarterback makes and the number of yards he throws the ball. The line passes through (24, 127) and (36, 163) and has a slope of 3.

What is equation of the trend line?
y = 3x + 79
y = 3x + 55
y = 3x + 65
y = 3x + 31

Use y = mx + b with m = 3. Plug in (24,127): 127 = 3(24) + b → 127 = 72 + b → b = 55.
So the equation is y = 3x + 55.
