The direct variation equation is y = kx.
In this case, the equation is y = 1.8x.
Substitute the given points into the equation. If the x and y coordinate of a point satisfies the equation and both sides are equal, then that point is your answer.
Estimation would be 90 x 70
Which is 6300.
Real answer of 92 x 68
= 6256

Well in order to round 9.42 to the closest whole number we must know that. anything below 5 we round down and 5 and up we round up
So 9.42 becomes 9
of if your wanting to round to the nearest tenth it would be 9.4 you drop the 2 because you rounded down since it was lower than 5.
