Do you want the equation of a line that passes through the given points? If so.....
slope = (change in y's) / (change in x's)
slope = (2 - 5) / (3 - 9)
slope = (-3) / (-6)
slope = 1/2
Now we know a point, (3,2) , and the slope, 1/2 , so we can write the equation of this line in point-slope form.
y - 2 = (1/2)(x - 3) And we can get this in slope-intercept form. Distribute the 1/2 .
y - 2 = (1/2)x - 3/2 Add 2 to both sides.
y = (1/2)x + 1/2
