Find the slope first
slope=(2-1)/(-1+3)=1/4=.25
now use the slope and either point to write in point slope form
y-1=.25(x-2)
y-1=¼x-½
to rationalize all the denominators multiply by the last common multiple, here we get 4
4y-4=x-2
then put in the correct order
x-4y=-2
(4,-1) turns into (1,4) because the equation for that is (x,y)->(y•-1,x)
The correct question is
<span>In a circle with a radius of 3 ft, an arc is intercepted by a central angle of 2π/3 radians. What is the length of the arc?
we know that
in a circle
</span>2π radians -----------------> lenght of (2*π*r)
2π/3 radians--------------> X
X=[(2π/3)*(2π*r)]/[2π]=(2π/3)*r
the lenght of the arc=(2π/3)*3=2π ft
the answer is 2π ft
The answer is 361 to the third power
The correct option is b. No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
<h3>How to explain the information?</h3>
The figure is a parallelogram and one diagonal measure 28 units.
In this case, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
Therefore, the correct option is B.
