What is the equation of the line that passes through the points (0,-2) and (-4,4)

Step-by-step explanation:

Slope-intercept form: y = mx + b

Slope formula:

Given points: (0, -2), (-4, 4)

(0, -2) = (x1, y1)

(-4, 4) = (x2, y2)

To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.

First, let's find the slope. To do this, input the given points into the slope formula:

Simplify:

4 - (-2) = 4 + 2 = 6

-4 - 0 = -4

The slope is .

To find the y-intercept, input the slope and one of the given points(in this example I'll use point (0, -2)) into the equation and solve for b:

-2 = 0 + b

-2 = b

The y-intercept is -2.

Now that we know the slope and the y-intercept, we can write the equation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
