If y=5x-7, determine the value of y when x=-3

y = -22

Step-by-step explanation:

y=5x-7

Let x=-3 and substitute it into the equation

y = 5(-3) -7

Multiply

y = -15-7

y = -22

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
