(1) If xay² and y=3 when x=9; if x=25, then the positive value ofy is (a)5 (b) 8 (c) 16 (d) 32.​

its a straight line parallel to the time axis

sites:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the opening of this porabola is facing up
