If y varies directly as x, and y = 25 as x = 5, find y for the x-value 7.

step-by-step explanation:

sry but any answer choices

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
