First you have to find the slope by subtracting y2 in this case (2) from y1 (8) dividing it over the subtraction of x2 (-8) and x1 (4) then once you get that you pick a point whether it’s (4,8) or (-8,2), plot it using the slope given to you and you’re done.
So, if<span> the scale </span>factor<span> is </span>three<span>, then the dimensions of the new shape </span>will<span> be </span>three<span> times larger than ... What </span>impact<span> did this have on the perimeter? ... The </span>area<span> of a rectangle is </span>length<span> times </span>width<span>, so it's 5 x </span>3<span>, which is 15. ... When you're working with scale </span>factors<span>, </span>square<span> the scale </span>factor<span> to determine the </span>area<span> of the new figure.</span>
The circumference of a circle is 2•3.14(Pi)•R(radius) or 3.14(Pi)•D(diamater).
Since we have our diameter, 60, we need to multiply it by Pi.
60Pi is your answer.
I hope this helps!
