Best ResponseYou've already chosen the best response.0so firstly, you want to try and find the equation of the line in the form y = mx + b

Best ResponseYou've already chosen the best response.0from the graph, we can see that the y intercept (b) is 4

Best ResponseYou've already chosen the best response.0and we can find the slope by picking any two points which lie on the line and applying \[slope = \frac{ y2  y1 }{ x2  x1 }\]

Best ResponseYou've already chosen the best response.0okay cool :) so show me what you get for the equation of the line and we can go from there

Best ResponseYou've already chosen the best response.0Okay so I picked the points (1,2) and (0,2) then It would be 2  2/ 0 1 Right?

Best ResponseYou've already chosen the best response.1The answer is either y > 2x 4 or y > (1/2)x 4 because the dashed boundary line is shaded on the "above" section which indicated that this is a greater than situation.

Best ResponseYou've already chosen the best response.0@Directrix Thanks you! Thant makes sense. I'm sorry this is my first time doing this. So what do I do next to find the answer?

Best ResponseYou've already chosen the best response.0(1, 2) is correct, however (0, 2) does not lie on the line, I think you mean (2, 0), so try finding the slope again @Marilynmonroe

Best ResponseYou've already chosen the best response.1That does not seem to be of much help. Let me graph on another program. We could test points.

Best ResponseYou've already chosen the best response.0@Marilynmonroe did you work out the gradient again?

Best ResponseYou've already chosen the best response.0Yes would it be 0  2/ 2  1 = 2/1 ?

Best ResponseYou've already chosen the best response.0so you have \[\frac{ 0   2 }{ 2  1 } = \frac{ 2 }{ 1 } = 2\] but you set it up correct

Best ResponseYou've already chosen the best response.0but now that we have our m and b, we can sub these into y = =mx + b to find the equation the line

Best ResponseYou've already chosen the best response.0Okay so would it be y = 2x+ 4 ?

Best ResponseYou've already chosen the best response.1Finally, my answer. y > 2x  4
