y=-15x+900

Step-by-step explanation:

Let x be the number of minutes and y be the quantity of sand in the hour glass.

After 3 minutes,

Quantity of sand in the top half=855 ml

After 10 minutes , quantity of sand in the top half=750 ml

We have to find the equation which represents this situation.

Now, we get two points (3,855) and (10,750)

Slope formula : $m=\frac{y_2-y_1}{x_2-x_1}$

By using slope formula

Slope = $\frac{750-855}{10-3}=\frac{-105}{7}=-15$

The equation of a line with slope m passing through the point (x_1,y_1)

y-y_1=m(x-x_1)

The equation of line with slope -15 and passing through the point (3,855) is give by

y-855=-15(x-3)

y-855=-15x+45

y=-15x+45+855=-15x+900

Hence, the equation represents this situation is given by

y=-15x+900
