Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation [tex]\frac{y_{1} - y_{2}}{x_{1}-x_{2}}[/tex] then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)
Step-by-step explanation:
soln;
A(-8,1) = X1,Y1
B(7,1) = X2,Y2
now,
equation of circle ;
(X-X1) (X-X2) + (Y-Y1) (Y-Y2) =0
(x+8) (x-7) + (y-1) (y-1) = 0
x^2-7x+8x-56+y^2-y-y+1 = 0
x^2+y^2+x-2y-55 = 0 is the required equation
