Note that we added -5 to the x coordinate of P to get the x coordinate of P'
And we added 10 to the y coordinate of P to get the y coordinate of P'
So translating (7,2) using the same rules becomes :
( 7 + -5 , 2 + 10) = ( 2, 12)
add -5 to the x coordinate of P to get the x coordinate of P'
And then add 10 to the y coordinate of P to get the y coordinate of P'
So translating (7,2) using the same rules becomes :
( 7 + -5 , 2 + 10) = ( 2, 12)
