The distance between two points is the root of the sum of the squares of the differences in their corresponding coordinates. The equation of choice A is the usual formulation.

<em>Comment on answer choices</em>

Because the square of a number is the same as the square of its opposite, the formula in choice D is also correct.

7. Write the slope-intercept form of the equation of the line graphed below.

Stels [109]

Answer:

The answer to your question is $y = \frac{-1}{2} x - 1$

Step-by-step explanation:

Process

1.- Get to points of the line

A (-2, 0)

B (0, -1)

2.- Find the slope of the line

Slope = m = $\frac{y2 - y1}{x2 - x1}$

Substitution

m = $\frac{-1 - 0}{0 + 2} = \frac{-1}{2}$

3.- Find the equation of the line

y - y1 = m(x - x1)

Substitution

y - 0 = -1/2(x + 2)

Simplification

y = -1/2x - 1
