Answer:

(x + 4)² + (y - 9)² = 25

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 4, 9) and r = 10 ÷ 2 = 5, thus

(x - (- 4))² + (y - 9)² = 5², that is

(x + 4)² + (y - 9)² = 25

The equation of best fit is y = (-22/5)x + 10.

What is an equation of a line?

The equation of a line is given by:

y = mx + c where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The following coordinates are given:

Pick two coordinates.

(0, 10) and (25, -100)

The equation of best fit.

y = mx + c

Now,

m = (-100 - 10) / (25 - 0)

m = -110 / 25

m = -22/5

Now,

(0, 10) = (x, y)

10 = (-22/5) x 0 + c

c = 10

Now,

y = mx + c

y = (-22/5)x + 10

Thus,

Using the coordinates the equation of best fit is y = (-22/5)x + 10.

Which shows this price as a correct unit price? $3.60 for 4 watermelons.
Ganezh [65]

Answer:

$0.90

Step-by-step explanation:

You are solving for the price of one watermelon (a unit of watermelon).

What is given to you is the price of 4 watermelons, or $3.60. To solve, simply divide $3.60 with 4:

3.60/4 = 0.90

$0.90 is your answer.

Remember to add the hundredth place value (0), as money goes to the hundredth place value.
