Answer:
Explanation:
count from the center to the edge of the circle along the tiny squares to find the radius.
r = 7
center of circle: (-1, -2)
Don't forget to flip the sign when plugging in the center into the equation.
Don't forget to square the raduis (7*7 = 49)
(x + 1)^2 + (y + 2)^2 = 49
To find the slope of the line start at one point and do "rise over run"
slope = -4/6 or -2/3
The y-intercept is always the point along the y-axis
y-intercept = (0, 4) or 4
y = -2/3x + 4
Now plug in y to the circle equation to get the final answer.
(x + 1)^2 + (-2/3x + 4 + 2)^2 = 49
