y = -\frac{1}{2}x - 1

Step-by-step explanation:

Let's pick two points on the line: P_1(-4, 1) and P_2(2, -2). Let's calculate the slope of this line using these points:

m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}

With this value of the slope, we can write the general slope-intercept form of the equation as

y = -\frac{1}{2}x + b

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1

Therefore, the slope-intercept form of the equation is

y = -\frac{1}{2}x - 1

Arlecino [84]

Answer:

|x − 37,500| ≤ 4,500

Step-by-step explanation:

salary - 37,500 can be up  +4500 or as negative -4500

as much as means less than or equal to

We use absolute values to indicate this

|x − 37,500| ≤ 4,500

What is the relationship between the variance and standard deviation? variance is the positive square root of the standard devia
lana [24]

Variance of a continuous random variable X is defined as

\int\limits_D {(x-\mu)^2f(x)} \, dx

Standard deviation is defined as

\sigma =  \sqrt{Var(X)}

Hence standard deviation is the positive square root of variance.

Kisachek [45]

Answer:

Table C

Step-by-step explanation:

To find the constant of proportionality, you need to divide y by x

Table A has a constant of proportionality of \frac{1}{3} <em>which is 0.3333 repeating</em>

Table B has a constant of proportionality of \frac{3}{5} <em>which is 0.6</em>

Table C has a constant of proportionality of \frac{3}{10}<em> which is 0.3</em>
