The standard form of the equation of circle is:
(x – h)^2 + (y – k) ^2 = r^2
Where the center being at the point (h, k) and the radius
being r
Substituting the values to the equation:
<span>(-15 - (-7)) ^2 + (y – (-1)) ^2 = 13^2 </span>
64 + (y +1) ^2 = 169
(y +1) ^2 = 105
y + 1 = 10.247
<span>y = 9.247</span>
Answer:
-9 ≤ y ≤ 8
Step-by-step explanation:
look at the endpoints of the segment; (7, 8) and (-2, -9)
the y-values represent the range and they go from -9 to 8, inclusive
Answer:
The equation would be y = 2x - 8
Step-by-step explanation:
The equation of the line would have a slope of 2, since parallel lines have the same slope. We can use that and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y + 2 = 2(x - 3)
y + 2 = 2x - 6
y = 2x - 8

There are pi radians in 180 degrees. Therefore to convert degrees to radians we need to divide by 180 and multiply by pi, as follows:
