What is the equation of the circle if the center is (-4,10) and radius of 7

(x+4)^2+(y-10)^2=49

Step-by-step explanation:

The standard equation of a circle is

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

where the center is (h,k) and r is the radius

so in this case h=-4, k=10, r=7

then we just plug them in

(x- -4)^2+(y-10)^2=7^2

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
