The equation of a circle always follows this:

(x - x1) + (y - y1) = r^2

x1 and y1 represent the coordinates as POSITIVE numbers and the r represent the radius

Your answer is (x + 1) + (y - 4) = 3

Answer:

(x + 1)² + (y - 4)² = 3

Step-by-step explanation:

The equation of a line 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) = (- 1, 4) and r = \sqrt{3}, hence

(x - (- 1))² + (y - 4)² = (\sqrt{3} )², that is

(x + 1)² + (y - 4)² = 3 ← equation of circle

Write the equation in standard<br> form of the line that has<br> x-intercept 6 and y-intercept -2.
zysi [14]

Answer:

<em>x - 3y = 6</em>

Step-by-step explanation:

<u>Equation of the line in intercept form</u>

The intercept form of the equation of a line is:

\displaystyle \frac{x}{a}+\frac{y}{b}=1

Where:

a = x-intercept

b = y-intercept

The standard form of a line is:

Ax + By = C

The given line has a=6 and b=-2, thus:

\displaystyle \frac{x}{6}+\frac{y}{-2}=1

Multiplying by 6:

x - 3y = 6

This is the required standard form of the line.

Thus, the standard form of the line is:

x - 3y = 6
