The equation y minus two-thirds = negative 2 (x minus one-fourth) is written in point-slope form. What is the equation in slope-
Lena [83]

Answer:

(B)  y=-2x+ \dfrac{7}{6}

Step-by-step explanation:

Given the point-slope form of the equation of a line below:

y-\dfrac{2}{3}=-2\left(x- \dfrac{1}{4}\right)

We are required to write it in the slope-intercept form, y=mx+c.

y-\dfrac{2}{3}=-2\left(x- \dfrac{1}{4}\right)\\\\y-\dfrac{2}{3}=-2x+ \dfrac{2}{4}\\\\y=-2x+ \dfrac{2}{4}+\dfrac{2}{3}\\\\y=-2x+ \dfrac{7}{6}

The slope intercept form is:

y=-2x+ \dfrac{7}{6}

<u>The correct option is B.</u>

How much string would you need to go around of a hat shaped like a cone if the radius is 4 inches? ( Use 3.14 for pi)
Paul [167]
The answer is b. 25.12
because we are finding the amount of rope to go around the circle, we are looking for the circumfrence of the circle, and the formula for the circumfrence of the circle is diameter(pi). because the radius of the circle is 4 inches, the diameter iss 8 inches because the diameter is 2(radius) and using multiplication, we can find the the circumfrence to be 25.12 inches
