Find slope of a straight line 2x-5y+7=0

Show that the points (a+5,a-4),(a-2,a+3) and (a,a) do not lie on a straight line of any value of a .

There are 11 points on a plane with 5 lying on one straight line and another 5 lying on a second straight line which is parallel to the first line. The remaining point not collinear with any two in the previous 10 points. The number of triangles that can be formed with vertices chosen from these 11 points

What will be the equation of the straight line that passes through the intersection of the straight lines 2x - 3y + 4 = 0 and 3x + 4y - 5 = 0 and is perpendicular to the straight line 3x - 4y = 5?

Prove that the locus of a moving point, which is equidistant from the lines 3x-2y=5 and 3x+2y=5 , is a straight line.

find the equation of the straight line passing through (2,1) and bisecting the portion of the straight line 3x-5y=15 lying between the axes.

Find the maximum number of points of intersection of 7 straight lines and 5 circles when 3 straight lines are parallel and 2 circle and concentric.

Fouation of the pair of straight lines through origin and perpendicular to the pair of straight lines 5x^(2)-7xy-3y^(2)=0 is
