A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand. Using a calculator might also be more time-efficient because it might accept a line in any form. A calculator’s window can be adjusted quickly instead of having to redraw a graph by hand when adjusting the scale.

What is the coordinate of the circumference of the circle? Question 2 options: (-3, -1) (1/2, -1/2) (1/2, 0) (0,0)
Norma-Jean [14]

Answer:

The circumcentre of the circle is (0.5,-0.5)

Step-by-step explanation:

Since this is a right triangle, UW is its diameter.

<u>CONCEPT :</u> The angle subtended by the diameter at the circumference of the circle =90°

Hence , center of circle is midpoint of line segment UW.

U(-3,2) and W(4,-3)

Taking the midpoint ,

C((\frac{-3 + 4}{2} ,\frac{2-3}{2} )

Center is C(0.5,-0.5) .

Radius = CV = \sqrt{(-2.5)^{2}+(-3.5)^{2}}

        R = \sqrt{\frac{37}{2} }

Equation of circle is (x - 0.5)^2 + (y+0.5)^2 = \frac{37}{2}

The circumcircle of triangle is (0.5,-0.5)
