Which is the equation of a line that has a slope of negative two-thirds and passes through point
(–3, –1)?

The equation of a line is .

Solution:

Given slope, m = and passes through the point (–3, –1).

Equation of a line passes through one point and slope formula:

Here, and

Substitute these in the given formula, we get

⇒

⇒

Cross multiply the fraction.

⇒

⇒

Subtract 3 on both sides of the equation.

⇒

⇒

Divide by 3 on both sides of the equation.

⇒

Hence, the equation of a line is .

D) y = -2/3x - 3

I just took the quiz on edge

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
