Question 769619: Select the equation of the line that passes through the given two points. Note that the correct equation may not be in slope-intercept form (solve for y to get the slope-intercept form).
11. (-6,8),(10,-56)
A y = -4 - 16x
By = - 16
C4x + y = -16
D2x + y = 16
E y = -6 - 8x
F y = -16 + 4x
12. (4,5), (19,-7)
A -12x = -123 + 14y
B-12x = -123 + 15y
C-6x = 19 + 5y
D4x + 5y = 41
E 5x + 5y = 10
F -16x = 312 - 19y

You can put this solution on YOUR website! The equation of line in slope-intercept form is 
with a number  that is the slope,
and a number  that indicates the y-intercept, meaning that the line passes through (0,b).
11. The slope of the line that passes through (-6,8) and (10,-56) is
There are many lines with a slope of  , but a line that passes through those two points must have a slope of , so we can eliminate of the choices that have a different slope.
A  is in slope-intercept form and has a slope of 
B  is in slope-intercept form and has a slope of 
  can be transformed into the slope intercept form
--> and has a slope of 
D  can be transformed into the slope intercept form
--> and has a slope of 
E  is in slope-intercept form and has a slope of 
F  is in slope-intercept form and has a slope of
