This is involving the equation of a line through a given point, parallel to a second line.  Assume that the line passes through the point (-3,-2) and is parallel to the line through the points (5,-1) and (-2,-5).
Find the equation of this line in slope intercept form. 
y=

anonymous · Answer

Slope of line through (5,-1) and (-2,-5) = (-5+1)/(-2-5) = -4/-7 = 4/7

So, parallel line through -3,-2 will have same slope.

y = 4x/7 + b
-2 = 4(-3)/7 + b
b = -2 + 12/7
b = (-14+12)/7
b = -2/7

y = 4x/7 - 2/7
=> 7y = 4x - 2

In slope-intercept form, 

y = (4/7) x - (2/7)
