Question

The point-slope form of the equation of the line that passes through (-9, -2) and (1.3) is y-3=1/2(x-1). What is the slope-intercept form of the equation for this line?

Answer 1

y = 1/2x + 5/2

Explanation:

y-3=1/2(x-1).

To get from point slope to slope intercept, distribute the slope

y-3 = 1/2 x -1/2

Then add 3 to each side

y-3+3 =1/2 x -1/2 +3

y = 1/2x +2 1/2

Or if we want the last term as an improper fraction

y = 1/2x + 5/2
