Sol.
Slop = x2 - x1 / y2 -y1. m mean slop
X1 = 1 , x2 = 3
Y1 = 2 , y2 = 4
m = x2 - x1 / y2 -y1
m = 3-1 / 4-2
m = 1
Y-Y1 = m ( x -x1)
Y-2 = 1(x-1)
Y = -1+2
Y = 1 ans
Qno. 2 + 2(2+2x0) + 2 x 0
Sol. 2 + 2(2) + 2 x o
2 + 4 + 0 = 6 ans
Qno. -6^2 / 3^2 (8-2x2)
Sol. 36 / 9 (8-2x2)
4.(8-4) = 16 ans
Qno. 3 + (-3) x 4 or (3+(-3)4
Sol. 3 + (-12)
3 - 12 = 9 ans
Qno. 2 + 6 / 2 x 3
Sol. 2 + 3 x 3
2 + 9 = 11 ans
