Answer:
3
Step-by-step explanation:
Points A and B lie on the horizontal line y = 1. The length of segment AB is then the difference of the x-coordinates of the points:
5 -2 = 3
The length of side AB is 3 units.
<span>m/5 + 3(m - 1) = 2(m - 3)
m + 15(m - 1) = 10(m - 3)
m + 15m - 15 = 10m - 30
6m = -15
m = -15/6</span>
Im not sure what slope means but if it means gradient then the gradient is 3x.
Answer: they are the same!
Think about this, if R lies on segment YX then the slope of YX and YR is the same, it doesn't matter where R is on the line (I hope I understood the question right if I didn't I'm sorry!)
The circumference of a circle is π × diameter, so if the radius is 8, that means the diameter is 16. If you want an estimate, you could do 16 × 3 = 48, which is probably more accurate. I hope this helps!
