For which equation does the point (10,74) lie on the graph?

equations ???
yea equations
to check it you have to replace x and y by (10,74) <--this order pair where first number is x and 2nd one is y and if you get both side equal then that is your answer
which equations ?? do u have answer choices or any equation
yes
so replace x and y into that equations
so to do it substitute point corrdinates (x, y) into equation and check if it will be true
like examle equation y=3x-9 substitue 74=3*10-9 and check if it is coorrect
@Daina900 did you understand ?? :)
the equations are D=2.4t+32 ,D=4.2t+32 ,D=6t+32
oka lets do first one together lets say D= y T= x
|dw:1423934878811:dw| replace variables by their values substitute 74 into D and substitute 10 into x
