Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = –2x2 +6x – 1.

x = 3; vertex: (3, 35)]

x = –1.5; vertex: (–1.5, – 14.5)

x = 1.5; vertex: (1.5, 3.5)

x = –1.5; vertex: (–1.5, –5.5)

Find the value of x for which the lines are parallel.

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab
