Which system of inequalities is graphed below?
2x – 3y > –27 x + 5y < 15 2x – 3y < –27 x + 5y < 15 2x – 3y greater than or equal to –27 x + 5y less than or greater to 15 2x – 3y less than or greater to –27 x + 5y less than or greater to 15
Observe that both lines are dotted. So your equations must have oly < and > that means, you can strike off last two options from possible answer
Ok would it be the second answer??? im kinda lost
its either first or second
figuring out is easy, let me think a bit
look at the graph again both are shaded down so you must have < in both equations (when u turn them to y = mx + c form)
Ok so if its shaded down its < and if its shaded up its > i understand Now!
Isnt the second optiond the one with 2 <
lets try second option :- 2x – 3y < –27 -2x+3y > 27 y > something ------------(1) x + 5y < 15 y < something -----------(2)
you got two different signs, so its not the second option.
coz, (1) has >, so graph has to SHADE up. but u dont have any shading up in the graph. so ditch 2nd option
2x – 3y < –27 x + 5y < 15 this is the answer? same sign twice
u need to look same sign twice after converting the equations to y=mx+c form
Oh so the sign switches
yes, i did that above, have a look. and didnt get same sign twice for these
ok so the answer would be 2x – 3y > –27 x + 5y < 15 the sign switches on the top one?
exactly !!
Thank you!
