will the point 81 satisfy the inequality of xy10 yes or noSo
will the point (-8,-1) satisfy the inequality of x-y>10? yes or no?
Solution
You just have to plug the numbers in and see if it is true.
 
 (x, y) = (-8, -1)
 
 0. Write out equation: x - y > 10
 
 1. Plug in values for x and y: [-8] - [-1] > 10
   
 2. Simplify. [-8] + [1] > 10
 
 3. Simplify -7 > 10
 
 4. Evaluate. Does this make sense? NO. -7 is less than 10, but the equation says it is greater than.
