What is the equation of the following line? be sure to scroll down first to see all answer options
andreyandreev [35.5K]

Answer:

The equation for the following graph:

y = -\frac{1}{5}x

Step-by-step explanation:

- You first need to find the slope by using the <u>slope formula</u>:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

(where (x_{1},y_{1}) is the first point and (x_{2}, y_{2}) is the second point)

-Use the given points (0,0) and (10, -2) from the graph for the formula:

m = \frac{-2 - 0}{10 - 0}

Then, you solve:

m = \frac{-2 - 0}{10 - 0}

m = -\frac{1}{5}

After you have found the slope, use the slope -\frac{1}{5} and the first point (0,0) for the <u>point-slope formula:</u>

y - y_{1} = m ( x - x_{1})

<u>(</u>where m is the slope and (x_{1}, y_{1}) is the first point)

y - 0 = -\frac{1}{5}  ( x - 0)

Then, you solve:

y - 0 = -\frac{1}{5}  ( x - 0)

y - 0 = -\frac{1}{5}x - 0

y - 0 + 0 = -\frac{1}{5} - 0 + 0

y = -\frac{1}{5}x

So, the equation for the following graph is y = -\frac{1}{5}x .

Julio makes a scale drawing of the kitchen floor to determine how
tatuchka [14]

The scale drawing of Julio's kitchen would change the kitchen size

The actual area is 243 square feet

<h3>How to determine the actual area of Julio's kitchen?</h3>

The parameters are given as:

  • Length = 4.5 inches
  • Width = 3.375 inches

Start by converting the dimensions to feet using the scale ratio

  • Actual length = 4.5 inches/ (1 inch/ 4 feet) = 18 feet
  • Actual width = 3.375 inches/ (1 inch/ 4 feet) = 13.5 feet

The area is then calculated as:

Actual Area = Actual length * Actual Width

This gives

Actual Area =18 feet * 13.5 feet

Evaluate the product

Actual Area = 243 square feet

Hence, the actual area is 243 square feet
