.

Substitute the values  x= -5  and  y= 5  into the left side formula and calculate.

When you complete calculations,  compare your result with the right side value.

given: the point (-5,5)= (x,y)
does it satisfy the inequality 16x+%2B+13y+%3C+-15:
16%28-5%29+%2B+13%2A5+%3C+-15
-80+%2B+65+%3C+-15
-15+%3C+-15-> false; Since -15+=+-15 point does not satisfy the inequality 16x+%2B+13y+%3C+-15
