The equations for two sides of a parallelogram are -x+10y-42=0 and 3x-y+10=0. Find the equations for the other two sides given that the point (6, -1) is a vertex of the parallelogram, Give your answer in general form.

Question

phi · Answer

Did you make any progress?

phi · Answer

I would put both equations into  the form
y = mx + b
so that you can see what the slope of each line is (the "m" value)

phi · Answer

Maybe make a rough sketch of the lines
then plot the point (6,-1)

the other two sides of the parallelogram will be parallel to the given lines, and go through the given point (6,-1)
you could use the point-slope formula
y - y0 = m( x - x0)
to find the equation of these two sides.
then translate to general form

phi · Answer

I think general form is
Ax + By + C = 0
