Best ResponseYou've already chosen the best response.1do you know how to graph `y = 2x  2` ?

Best ResponseYou've already chosen the best response.1y = 2x  2 is a linear equation. Ie, a straight line

Best ResponseYou've already chosen the best response.1if x = 0 for instance, then y is... y = 2x  2 y = 2*0  2 ... replace x with 0 y = 0  2 y = 2 so we have the point (0,2). Do you see how I got this?

Best ResponseYou've already chosen the best response.1now use x = 1 if x = 1, then y = ???

Best ResponseYou've already chosen the best response.1you did it right

Best ResponseYou've already chosen the best response.1another point on this line is (1,4)

Best ResponseYou've already chosen the best response.1plot the two points (0,2) and (1,4). Draw a straight line through them since we have this sign ≥, which has a line under the ">", we will make this boundary line solid

Best ResponseYou've already chosen the best response.1yeah because of that underline

jim_thompson5910

Best ResponseYou've already chosen the best response.1IF there wasn't an underline, then it would be a dotted or dashed boundary line

Best ResponseYou've already chosen the best response.1we can use desmos to graph https://www.desmos.com/calculator

Best ResponseYou've already chosen the best response.1type `y >= 2x2` to mean \(\Large y \ge 2x2\)

Best ResponseYou've already chosen the best response.1as for the other inequality y + x ≥ 0 is the same as y ≥ x (Subtract x from both sides)

Best ResponseYou've already chosen the best response.1you'll need to graph y = x then shade above that solid boundary line

jim_thompson5910

Best ResponseYou've already chosen the best response.1notice how in your desmos graph, the shading is above the boundary line because of the > symbol

Best ResponseYou've already chosen the best response.1do you know how to graph y = x ?

jim_thompson5910

Best ResponseYou've already chosen the best response.1it's very similar to how we graphed y = 2x2

jim_thompson5910

Best ResponseYou've already chosen the best response.1if x = 0, then what is y when y = x ?

jim_thompson5910

Best ResponseYou've already chosen the best response.1so one point on it is (0,0)

jim_thompson5910

Best ResponseYou've already chosen the best response.1then if x = 1, y = ???

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1yep so we know the two points on it are (0,0) and (1,1)

jim_thompson5910

Best ResponseYou've already chosen the best response.1once you have y = x graphed, you shade above the boundary line why above? because of the > sign. This only works if y is isolated why is the boundary line solid? because there is an underline under the >

jim_thompson5910

Best ResponseYou've already chosen the best response.1now do both graphs at the same time

jim_thompson5910

Best ResponseYou've already chosen the best response.1the final step is to only shade where the two regions overlap one another

jim_thompson5910

Best ResponseYou've already chosen the best response.1yeah pretty much

jim_thompson5910

Best ResponseYou've already chosen the best response.1yeah you follow all those steps. Using desmos, or anything like it, is a good way to check the result
