What transformation is represented by the rule (x, y)→(−y, x)?

a. reflection across the x axis

b. rotation of 90 degrees clockwise about the origin

c. reflection across the y axis

d. rotation of 180 degrees about the origin

C. reflection of the y axis, the y turned from a positive to a negative y while x is still the same

Hope I helped you:)

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
