Which list of ordered pairs represents solutions to x + y= 2 ?

(-4, 6), (0, 2), (4,2)

(-4,-6). (0, 2), (4,2)

(-4, 6), (0, 2), (4,-2)

(-4, 6), (0, 2), (4, -2). You can find this by adding the x and y to see which ones get 2. -4 + 6 = 2. 0 + 2 = 2. 4 + -2 = 2.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

answer is c
