You water the plants in your classroom at a constant rate. after 5 seconds, your watering can contains 58 ounces of water. fifteen seconds later, the can contains 28 ounces of water.

a. write an equation in slope-intercept form that represents the amount yy (in ounces) of water in the can after xx seconds.

y = -3x + 142

Step-by-step explanation:

We can write the information given to us as ordered pairs, where x represents the number of seconds and y represents the amount of water in the can:

(5, 58) and (15, 28)

To write an equation in slope-intercept form, first we find the slope.  The formula for slope is:

Using our points, we have

We use point-slope form to write the initial equation:

Using our first point as (x₁, y₁), we have:

y-58 = -3(x-28)

Using the distributive property, we have

y-58 = -3(x)- -3(28)

y-58 = -3x+84

Adding 58 to each side, we have

y-58 + 58 = -3x+84+58

y = -3x + 142
