Isaac wants the equation below to have no solution when the missing number is placed in the box. which number should he place in the box?

ANSWER

EXPLANATION.

The given equation is

Let us expand the right hand side to obtain:

We group similar terms and keep the expression with the box on the left.

Simplify

We can see that the value of box the will be the equation to have no solution is 4.

Let us substitute 4 for box.

This is not true. Hence the equation has no solution when

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:
