If you rotate about the circumcentre of a regular polygon 72° it will overlap with the original image.
Answer: step-by-step
Step-by-step explanation:
answer: 10
to solve you have to follow PEMDAS
Answer:
y = -1/4x+2
Step-by-step explanation:
We can find the slope by finding two points on the line, and doing (y1-y2) ÷ (x1-x2). The two points I chose were (0,2), and (4,1). We can plug this into the equation to get (2-1) ÷ (0-4), to get -1/4, which is our slope. We can see on the graph, that the line intersects with the y axis when the y coordinate is 2, making the y-int 2.
Simple....
you have:
(-15,70) and (5,10)
Using-->>


Using y=mx+b...and any of the coordinates....
70= -3(-15)+b
70=45+b
70=45+b
-45 -45
25=b
y=-3x+25
Thus,your answer.
Answer:
1. (-4,0) (0,2)
2. (6,0) (0,3)
3. (-4.5,0) (0,-3)
