Select the point that lies within the solution to the graph of y > β3x + 4? (β1, 7) (0, 3) (1, 3) (3, β6)
so you're given two values in each subset, an x and y, plug in both numbers to see if the equation is true. i'll show you what i mean with the first one 7 > -3(-1) + 4, now just solve the equation
7>3+4?
exactly and when you add 3 and 4 together you get 7 so it's saying 7 > 7, is that true?
nope...3>-3(0)+4=3>4... not true either
isnt this > greater than?
yeah! it's true :)
sorry i looked at it wrong, i tried to delete it as soon as i posted it haha, you were right :)
lol i was like hmmmm im not good in math but im pretty sure > means greater than
my baaad :D
Checking (-1,7) y > β3x + 4 7 > β3(-1) + 4 7 > 3 + 4 7 > 7 ... false ---------------------------- Checking (0,3) y > β3x + 4 3 > β3(0) + 4 3 > 0 + 4 3 > 4 ... false ---------------------------- Checking (1,3) y > β3x + 4 3 > β3(1) + 4 3 > -3 + 4 3 > 1 ... true ---------------------------- Checking (3,-6) y > β3x + 4 -6 > β3(3) + 4 -6 > -9 + 4 -6 > -5 ... false ---------------------------- So the answer is choice C
thanks!
What is the slope of the line x = β5?
this is a vertical line, so the slope is undefined
lol wow i feel slow
