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)

2

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
