Answer:
30 degrees
Step-by-step explanation:
90 + 60 + x = 180
150 + x = 180
-150 -150
x = 30
You got the dot on the right spot, the coordinates are (1.5,2.5) because you reflected across the x axis so the y coordinate changed. The distance between them are 5, because you move half of a unit two times which equals 1 whole unit and 4 whole units. 4+1=5
Answer:+0.5 is the slope
Step-by-step explanation:
(-2,-4) (-1,-3.5) (0,-3) (1,-2.5) (2,-2)
The correct answer is 127.
:)
Slope is

Then you use the equation

Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):

You know m (from above) and now you can solve for b.
Rearrange terms:

And that will be the answer.
Make sense?
