How do i do this? i don't get this very much

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
