Answer:

$y = -\frac{1}{4}x$

Step-by-step explanation:

1. The slope-intercept form of a linear equation is $y = mx + b$ , where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.

2. To find the slope, let's take the two points (0,0) and (-40,10). After that, let's plug in the values to their corresponding variable in the formula: $\frac{y_2-y_1}{x_2-x_1}$

$\frac{10-0}{-40-0}$
$\frac{10}{-40}$
$-\frac{1}{4}$

3. Since we now know our slope, the equation looks like this so far: $y = -\frac{1}{4}x + b$ .

4. Because b is the y-intercept, b = 0 because the line intersects the y-axis at (0,0).

5. Now that we have the values of m and b, we plug in them to get the equation of: $y=-\frac{1}{4}x$

Find the Exponential Regression using the table. Write the initial amount, common ratio, and equation for the table.

Triss [41]

Answer:

Initial temperature;

432.76

Common ratio;

-0.067

Equation;

$y=432.76e^{-0.067x}$

Step-by-step explanation:

In this scenario, the time in minutes represents the independent variable x while the temperature of the pizza represents the dependent variable y.

The analysis is performed in Ms. Excel. The first step is to obtain a scatter plot of the data then finally inserting an exponential trend line to obtain the required equation.

The Ms. Excel output is shown in the attachment below. To obtain the initial temperature we substitute x = 0 in the equation. On the other hand, the common ratio is the exponent in the equation.
