Answer:

y + 1 = 2 ( x - 6)

Step-by-step explanation:

This is the answer because the formula for Point-Slope is y-y1=m(y-y1)

all you have to do is substitute the given information into the formula to get your answer

Answer: y + 1 = 2(x-6)

Step-by-step explanation:

Point Slope Form is y-y₁=m(x-x₁), and all you have to so is substitute in the values that you were given. So, the slope is 2, so you substitute that value in for m. Then, you substitute 6 in for x₁ (because 6 is the x value of the coordinate you were given) and you substitute -1 for y₁ (and it becomes positive because two negatives make a positive)

Hope this was helpful! Please feel free to ask me any questions!

Find the circumference of each circle. Use 3.14 for the value of π . Round answer to the nearest tenth.
kvv77 [185]

Answer:

C=9.4\pi meters

Step-by-step explanation:

Recall to find the circumference of a circle the formula is C=\pi d or C=2\pi r.

We start by substituting 4.7m for r in the second circumference formula.

C=2\pi r\\C=2\pi (4.7)\\C=9.4\pi. We input this value of r into the area formula.
