Question

Which of the following inequalities matches the graph? graph of an inequality with a dashed line through the points (0, 3) and (1, 9) with shading above the line

Answer 1

(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
