Answer:

(9/2, 7/2)

Step-by-step explanation:

The easiest way to remember how to do this problem is to average the x-coordinates and average the y-coordinates.

So, in your problem (-3 + 12)/2 = 9/2   and  (-5 + 12)/2 = 7/2

The midpoint is (9/2, 7/2)

Answer:

5) a

6) a

7) b

8) d

9) a

10) b

11) c

12) a

Step-by-step explanation:

When it asks for range it is asking for the y values so when you plug in numbers such as 0,1,2 into the equation the y values you get are {0,90,180..}

Overall slope can be found by taking the x and y values of the two given points.

((y value of the second point)-(y value of the first point))/((x value of the second point)-(x value of the first point))

Using (1,2) and (-2, 5) you can do this by plugin in the numbers (5-2)/(-2-1)

So the slope will be 3/-3 = -1

Once you find the slope you can use this to find the equation of a line by pluging in values into y=mx + b

m = slope

y = use this from the points given

x = use this from the points given

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y-3 = {(x - 1). What is the slope-in
GrogVix [38]

Answer:

y=1/2x - 1/2

Step-by-step explanation:

Slope intercept form is y=mx+b

The m is the slope of the line and the b is the y-intercept.

You must first the slope. The formula of a slope is (y1-y2)/(x1-x2). In this example it is (-2-3)/(-9-1) which equals 1/2. By order of elimanation we can see that y=1/2x-1/2 is correct.

Find the area of the figure.
Gelneren [198K]

Answer:

64 + 28 = 92

Step-by-step explanation:

Split the figure in half creating two triangles and a square.

length and width for the square would be 8ft and 8ft. Multiply both for 64 to be the area.

7ft and 4ft are the height and base for the triangles.

In this case, just multiple 7 and 4 because normally you would need to divide the product by 2 however since there are two triangles it negates the step.
