Evaluate the algebraic expression a + b - c when a = 3, b = 5 and c = 7. A. 15 B. 9 C. 6 D. 1

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
