Graph the line that contains the point (-5,-3) and had a slope of -2
Ipatiy [6.2K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: Is the slope

b: Is the cut-off point with the y axis

According to the data of the statement we have to:

m = -2

Then, the equation is of the form:

y = -2x + b

We substitute the point(x, y): (- 5, -3)and find "b":

-3 = -2 (-5) + b\\-3 = 10 + b\\-3-10 = b\\b = -13

Finally, the equation is:

y = -2x-13

To graph we place the points (-5, -3)and(0, -13) on the coordinate axis and join the points by a line.

ANswer:

y = -2x-13

The graphic is attached.

matrenka [14]

Answer:

4 inches

Step-by-step explanation:

First, we find how much fits into one inch of soil. We do this by multiplying 4 by 3. This equals 12. For every 12 cubic inches, the soil will be one inch deep. We divide 48 by 12 to see how many inches deep is it. This equals 4. The soil is 4 inches deep.
