We have to write the equation of the line, in point-slope form. Given an identified point (x1, y1) as the point (-2, 2). So that means x1=-2 and y1=2
Value of slope "m" is not given so i will keep using "m" for the slope. In case value of slope m is given in the problem then you can plug that number in place of m.
Point slope formula is given by:

plug the given values into above formula :


so the required answer in point slope form is 
Sarah had $49 dollars, plus the money her mom had.
I dont' know im soooo sorry for not knowing
7/8 / 2/7 =
7/8 * 7/2 = 49/16 = 3 1/16
