Help. Giving Out Medals ;) PLEASE HELP!!

A line passes through (-7,-5) and (-5,4). Write an equation for the line in point-slope form. Rewrite the equation in standard form using integers.

A. y+5= 9/2 (x-7); -9x+2y=53
B. y+7= 9/2 (x+5); -9x+2y=31
C. y+5= 9/2 (x+7); -9x+2y=53
D. y-5= 9/2 (x+7); -9x + 2y=-53

Answer 1

m = y2 -y1/x2-x1 = (-5) - 4/(-7)-(-5) = -9/-2 = 9/2

Answer 2

y - y1 =m ( x - x1) = 0
since y1 = -5 then:
y - (-5) =9/2( x - (-5)) = 0
y + 5 = 9/2 (x + 5)
sorry to tell you answers are wrong..it happens sometimes
