Tell whether the given ordered pair is a solution of each equation.

Question

1. 3x + 5 = y; (1, 8)

2. y=(x−1.2)(−3); y equals ( x-- 1.2) ( - 3 ) ; (0, 1.2)

I don't understand

Answer 1

you take the given (x,y) pair and plug it into the equation to see whether it is true.
#1. 3*1 + 5 = 8
true

#2. 1.2 = (0-1.2)(-3) = 3.6
false
why do you repeat the equation, using "equals" ?
