Which of the ordered pairs
(0, 0), (–2, 10), (–1, –5), (–3, 9)
are solutions for the equation y = 5x?
:
you can do this, not at all hard. The 1st value in the pair is x, the 2nd is y
:
Take the pair (0,0), substitute 0 for x in the equation
y = 5x
y = 5(0)
y = 0, so (0,0) is a solution:
:
The next pair: (-2,10), substitute -2 for x in the same equation
y = 5x
y = 5(-2)
y = -10, not +10 so it is not a solution
:
The next pair (-1,-5)
y = 5(-1)
y = -5, so this is a solution
:
The next pair (-3,9)
y = 5(-3)
y = -15 so this is not a solution
:
How about this, can you do this now?
