If the straight line y = mx +c passes through the points (2,4) and (-3,6) , find the values of m and c .

If the straight line (x)/(a)+(y)/(b)=1 passes through the line point of intersection of the lines x+y=3 and 2x-3y=1 and is parallel to x-y-6=0, find a and b

What will be the value of m and c if the straight line y=mx+c passes through the points (3, -4) and (-1, 2) ?

If a , b ,c are in harmonic progression, then the straight line (x/a)+(y/b)+(1/c)=0 always passes through a fixed point. Find that point.

If a , b ,c are in harmonic progression, then the straight line ((x/a))+(y/b)+(1/c)=0 always passes through a fixed point. Find that point.

If a , b ,c are in harmonic progression, then the straight line ((x/a))+(y/b)+(l/c)=0 always passes through a fixed point. Find that point.
