the curve y=ax^2 + bx passes through (2,0) and (4,8). find a and b.

the line y=mx+c passes through (2,5) and (4,13). find m and c.

the line with equation y+ax=c, passes through the points (1,5) and (3,1). find a and c. hint : for the point (1,5) . put x = 1 and y=5 into y+ax=c, etc.

just want to know how to prove it..

consider line 4x-3y+12=0,find the equation of the line passing through the point 1,2 and the parallel to the given line. and find the distance between these two parallel lines

Options: 1) x=2y,4x + 2y + 1=0 2) 2x + y =0, 2x = 4y + 1 3) x = 2y, 2x = 4y + 1 4) 2x + y =0, 4x + 2y + 1= 0

The three lines are concurrent and the answer is supposed to be (-1/6,-23/9).

Trigonometry Identities and equation

My answer is not matching. I got 16 units sq.

The ans given is isosceles.maybe there must be a small correction in question.so can anyone post the correct question so that ans is isosceles
