Answer:

Step-by-step explanation:

We can use the point-slope formula to write an equation for this line. The point-slope formula states :

where m is the slope and (x1 y1) is a point the line passes through .

We can substitute the slope and values from the point to give:

(y-1) = 8 (x-7)

We can also transform this equation to the slope-intercept form by solving for

. The slope-intercept form of a linear equation is: y=mx+b

where the m is the slope and b s the y-intercept value.

y-1= (8 times x) - ( 8 times 7)

y-1= 8x - 56

y-1 + 1= 8x- 56 + 1

y-0= 8x- 55

y= 8x - 55

The radius of a circle is 13 find its area un terms of pi

Leto [7]

The area of the circle is given as:

$A=\pi r^2$

Plugging the value of the radius we have that:

$A=\pi(13)^2=169\pi$

Therefore the area in terms of pi is:

$A=169\pi$

Which point lies on the circle represented by the equation (x+5) + (y-9) = 8

olga_2 [115]

Answer:

(-5,9+√8)

Step-by-step explanation:

There are two ways in which you can find a point that lies in the circle. One of them is to do y the subject of the formula, and another one is to determine the center of the circumference, and with the information of the radius, you can sum this value upward or downward.

the general equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$
