If a=-10;then:
a+1=-10+1=-9=b
-9>-10
if a=10; then
a+1=10+1=11=b
11>10
A)The pair of values for a and be are: a=-10, then the value of b would be: -9;
And a=10; then the value of b would be:11;
B) It isn´t possible to create a pair of values for a and be, in wich the numerical relationship shown in the given conditional stament is false, therefore b>a if a+1=b
(10,1250),(20,1400)
slope = (1400 - 1250) / (20 - 10) = 150/10 = 15
so every hr of training raises the salary by $ 15
OPTION A , C,D
are the correct choices because all of them are equal to √5
