this is just a matter of subbing and seeing which ones are true. Lets try the first one... x + 3y >= -8 (-5,-1)....x = -5 and y = -1 now we sub -5 + 3(-1) >= -8 -5 - 3 >= -8 -8 >= -8 --- correct because -8 = -8 so this is a solution. You want to try the next one ?

YES

x + 3y >= -8 (0,-3)...x = 0 and y = -3 now we sub 0 + 3(-3) >= -8 can you finish and see if it is true ?

-9 is less than -8 so false
texaschic101
  • texaschic101
wait...your sign is greater then or equal It is saying -9 is greater then or equal to -8....so it is false
freemap
  • freemap
sorry just looked at sign so it'll still be false because -9 is not greater than -8

  • texaschic101
keep this in mind....with positive numbers, the bigger the number, the greater it is...but with negatives, the smaller number is greater

x + 3y >= -8...x = -1 and y = -2 -1 + 3(-2) >= -8 -1 - 6 >= -8 -7 >= -8......this is true

I was just about to submit -7>=-8 which is true. Instead of me multiplying 3 *-2 I did 3*2

it takes practice and patience. You will one day be helping others learn this stuff. So your solutions are A,C,D because B and E were false....but you already knew this so why am I telling you...lol

Which is the graph of y ≤ 1 – 3x?
freemap
  • freemap
freemap
  • freemap
I said A because it has a solid line, and its less than so it goes to the left
texaschic101
  • texaschic101
y = -3x + 1 --- I just rearranged it and temporarily removed the < sign y intercept is 1 or (0,1) x intercept can be found by subbing in 0 for y.. 0 = -3x + 1 3x = 1 x = 1/3 ... or (1/3,0) now back to your signs....it contains an equal sign, so it is a solid line. It is < (less then) so shading occurs below (or to the left) of the line. the correct graph is : A...you are correct :)
