I believe it’s C.
The line y=x looks like a even, diagonal line going through (0, 0) on a graph. If you have (-7,3) , your in the first quadrant (in the upper left square of the graph). If you reflect it diagonally, the digits themselves would remain that same, but the value would flip (if it’s positive, it’ll become negative, if it’s negative, it’ll become positive). So if we do that with (-7, 3), it becomes (7, -3).
Solution: (7, -3)

Find the equation of the line that is parallel to the given line and passes through the given point. y=0,5x-2;(-2,1)
Mashcka [7]

Answer:

y = 0.5x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 0.5x - 2 ← is in slope- intercept form

with slope m = 0.5

Parallel lines have equal slopes, thus

y = 0.5x + c ← is the partial equation

To find c substitute (- 2, 1) into the partial equation

- 1 = - 1 + c ⇒ - 1 + 1 = 0

y = 0.5x + 0 , that is

y = 0.5x ← equation of parallel line

Angle C is inscribed in circle O. Line AB is a diameter of circle O. What is the measure of angle B? I can't get the picture but
WINSTONCH [101]

Answer:

Step-by-step explanation:

Since the inscribed angle theorem tells us that any inscribed angle will be exactly half the measure of the central angle that subtends its arc, it follows that all inscribed angles sharing that arc will be half the measure of the same central angle. Therefore, the inscribed angles must all be congruent.
