A rain barrel is full of water and used to water the garden. The rain barrel loses water at the rate 2.5 gallons of water per mi
soldier1979 [14.2K]
Answer: <span>y - 37.5 = 2.5 ( x - 7)

Explanation:

1) The point-slope form is has this form:

 y - y1 = m (x - x1)

Where m is the slope or rate of change and x1, y1 are the coordinates of the point.

2) you are told that the the rate of change of water (m) is 2.5

m = 2.5

3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:

x1 = 7
y1 = 37.5

</span>4) Replace those value in the point-slope model:

y - 37.5 = 2.5 ( x - 7)

That is the point-slope model or equation.

How long does a car traveling at 70 mph take to travel 88 miles, in hours
dybincka [34]
So,

Obviously, the car will travel 70 miles in one hour.  So after one hour, the car will have traveled 70 miles.  That leaves 18 miles.

The time it will take for the car to go another 18 miles will be 18 divided by 70.
\frac{18}{70}

Simplify.
\frac{2*3*3}{2*5*7}
\frac{3*3}{5*7}
\frac{9}{35}

Divide.
≈ 0.25714

So a car traveling at 70 mph will take approximately 1.25714 hours or 1.26 hours to travel 88 miles.

Find the slope of the line.<br> y = -10x - 2
Pavlova-9 [17]

The slope is the change in y-axis to x-axis of a graph. The slope of the line given is -10

<h3>How to find the slope of a line?</h3>

The standard equation of a line in slope intercept form is given as y = mx+b

where

  • m is the slope
  • b is the y-intercept

Given the equation y = -10x - 2

Compare

mx = -10x

m = -10

Hence the slope of the line given is -10
