(0,3)(1,9)
slope = (9 - 3) / (1 - 0) = 6/1 = 6
y = mx + b
slope(m) = 6
use either of ur points...(0,3)...x = 0 and y = 3
now sub and find b, the y int
3 = 6(0) + b
3 = b
ur equation is : y = 6x + 3
for an inequality, a dashed line means there is no equal sign in the problem...and shading above the line means greater then.
so ur inequality is : y > 6x + 3
