Sydney wrote the equation y+1=1/2(x−3). y + 1 = 1/2 ( x − 3 ) . explain her error and then write the correct equation in point-slope form. HELP PLEAS

See explanation

Step-by-step explanation:

Given that the correct point-slope form is;

y - b = m(x - a)

So she made an error in writing y + 1, that part is wrong.

So the equation that was written wrongly is;  y+1=1/2(x−3)

We have to rewrite the entire equation;

y - 1 = 1/2(x - 3)

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
