Okay so first off the equation of a line is
Y=mx+b
m= the slope
b= the y intercept

The Y intercept of this line is 2 and the slope is 5/3! You know this is the slope because if you start at point a and go up 5 and to the right 3, you end up at point b.

The equation for this line would be y=5/3x+2

Write the standard form of the equation of the circle with its center at (-5,0) and a radius of 8 what is the equation of the ci

Leto [7]

Answer:

$\large\boxed{(x+5)^2+y^2=64}$

Step-by-step explanation:

The standard form of an equation of a circle:

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

(h, k) - center

r - radius

We have the center (-5, 0) and the radius r = 8. Substitute:

$(x-(-5))^2+(y-0)^2=8^2\\\\(x+5)^2+y^2=64$
