Which of the following are point-slope equations of the line going through
(-2, -2) and (2, 1)?
---------------
slope = (1--2)/(2--2) = 3/4
Form:: y = mx + b
Solve for "b" when m = 3/4, x = 2 and y = 1
----------------
1 = (3/4)2 + b
b = -1/2
-------
Equation:
y = (3/4)x - (1/2)
---------------------

(-2,-2 )
( 2, 1 )
The slope is: [ change in y ] / [ change in x ]

-----------------------------
Use one of the given points in the
point-slope formula
( 2,1 )

Here's the plot:
