Circle equation
(x - h)^2 + (y - k)^2 = r^2
Since radius isn't given use the center and point, with the distance formula, to find the radius.
D=sqrt((x2-x2)^2+)y2-y1)^2)
D=sqrt((1-0)^2+(2-6)^2
D=sqrt(1+16)
D=sqrt 17
radius = sqrt 17
(h, k) is the center and r is the radius
(x - 1)^2 + (y - 2)^2 = 17
Answer:
I noticed that both of the lines had the same y-intercept and have different slopes leading to different amounts and the way that the line is shaped,like how the red line isn´t shaped in a straight line but the slope of the blue line led it to form in a straight line.
Step-by-step explanation:
Answer:
x=-2 and 2
Step-by-step explanation:
x^2-4=0
(x-2)(x+2)=0
x=-2 and 2
