1. No number 1

2.

10y=3x+15

M= 3/10= 0.3

C= 15/10 = 1.5

Answer,,,, option A.

3.

M= y₂-y₁ / x₂-x₁

= 3-7 / 6-2

= -4/4

=-1

B

4.

Midpoint = x₁+x₂ / 2, y₁+y₂/2

3-1/2, 5+9/2

2/2, 14/2

1,7

M= 9-5 / -1-3

M= 4/-4

M= -1

Y=mx+c

7= 1(-1)+c

7=-1+C

7+1= C

C= 8

y=-x+8


5.

Y-y₁=m(x-x₁)

y-1=-2(x-4)

y-1=-2x+8

Y=-2x+8+1

Y=-2x+9

Y+2x-9=0........ C


6.

5x-3=2x+9

5x-2x=9+3

3x=12

x=4

Put x=4

Y=5x-3

Y=5(4)-3

Y=20-3

Y=17

(4,17)...... C


8.

a=2, d=4

T₁₂ = a+11d

= 2+11(4)

= 2+44

=46......... A


9.

a+(n-1)d=90

2+(n-1)4=90

2+4n-4=90

-2+4n=90

4n=90+2

4n=92

n= 23........D
