2020 NECO MATHEMATICS (ESSAY) ANSWERS:
(1a)
Equation:
y – y1/x – x1=y2 – y1/x2 – x1
y – 5/x – 6 = 7 – 5/-2 – 6
y – 5/x – 6 = 2/-8 = 1/-4
y – 5 = 1/4(x – 6)
y – 5 = -1/4x + 6/4
y = -1/4x + 6/4 + 5
y = -1/4x + 3/2 + 5
y = -1/4x + 13/2
OR 4y = -x+26
X + 4y = 26
(1b)

S(2x + 9)dx
-1
= 2X¹+¹/1+1 + 9x]2
-1
= x²+9x]2
-1
=[2²+9(2)] – [(-1)² + 9(-1)]
=[4 + 18] – [1 – 9]
= 22 + 8
= 30
