does x+y<2;(1,1) satisfy the inequality

Question

test the given point to see if it satisfies the inequality

 

x+y<2;(1,1)

 

Answer 1

Hi Sherry,

 

Given the x and y values of (1,1) if we plug them into the equation, we get 1 + 1 = 2. This is not the same as x + y < 2, which means x plus y is always less than 2. Since are values of x and y give us a result equal to 2, this point does not satisfy the inequality.
