Answer:

Below is are attachments of positive,negative, and zero slopes. I could not provide an example of undefined, but basically what that is, is when the line is a straight line going down on either the right or left side of the graph.

Find the equation of the straigt line
natka813 [3]

Given :

A graph with a straight line on it.

To Find :

The equation of the line.

Solution :

From the given graph we can see that the line passes through point ( 0,6 ) and ( 4,10 ) .

Also, equation of line passes through two points (x_1,y_1) and ( x_2,y_2) is :

y - y_1 = (\dfrac{y_2-y_1}{x_2-x_1})( x - x_1)

Putting all given values, we get :

y - 6 = (\dfrac{10-6}{4-0})( x -0)\\\\y - 6 = x\\\\y -x = 6

Therefore, the equation of line is y - x = 6 .

The annual snowfall in city A is 58.7 inches. This is 12.5 inches more than six times the snowfall in city B. Find the annual sn
Lelechka [254]
The annual snowfall for city B is 7.7 inches. 
Since it is 12.5 inches more: 58.7 - 12.5 = 46.2
Since 46.2 is 6 times that of city B: 46.2 / 6 = 7.7

Help with geometry..need help...if any of you is good with geometry
aev [14]

Answer: For the first image, D will be the correct answer. For the second image, A will be the correct answer.

Step-by-step explanation:

The first image has a quite simple answer because translating the shape just means moving every point in the direction given according to some many units. In this case, we would be translating points A(-4,3), B(-3,1), and C(-1,2) 5 units right and 5 units down to get us the prime points of A'(1,-2), B'(2,-4), C'(4,-3).

In the second image, a reflection just describes a flip over some line, known as the line of reflection. We change the point's signs depending on the line of symmetry we are given when reflecting (in this case, the y axis). Reflecting the trapezoid over the y axis will result in a change of signs of the x values of the given points. Point A of the trapezoid is located on coordinate (-2,2), after the reflection, it will be located on point (2,2). Points B will reflect from point (-1,2) to point (1,2). Point C will reflect from (-1,1) to (1,1). Finally, point D will reflect from point (-3,1) to (3,1). After this reflection, we have to perform the same one except only the y values of our coordinates will change because we are reflecting over the x axis. After you graph the trapezoid from the previous reflection, do the same thing by just changing the y values of the coordinates to get your desired image.
