Evaluate the expression for the given value of the variable. 51 + 3/7r. r= - 1/2

The answer is -50.429

You would replace the -1/2 where r is at, divide 7& -1/2, then add it to 51

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
