Accepted Solution
A:
Answer:B and CStep-by-step explanation:y - 1 = -2(x - 2)y - 1 = -2x + 4y = -2x + 4 + 1y = -2x + 5now we subA. y = -2x + 5...(0,-2) -2 = -2(0) + 5 -2 = 5...nope, not this one, no need to go further on this oneB. y = -2x + 5 ...(0,5) y = -2x + 5...(-2,9) 5 = -2(0) + 5 9 = -2(-2) + 5 5 = 5.....yep 9 = 4 + 5 9 = 9...yep so B is a correct answerC. y = -2x + 5....(-1,7) y = -2x + 5...(2,1) 7 = -2(-1) + 5 1 = -2(2) + 5 7 = 2 + 5 1 = -4 + 5 7 = 7...yep 1 = 1...yep so C is a correct answerD. y = -2x + 5....(3,-1) y = -2x + 5...(2,-1) -1 = -2(3) + 5 -1 = -2(2) + 5 -1 = -6 + 5 -1 = -4 + 5 -1 = -1...yep -1 = 1......nopeso ur answers are : B and C
