linear inequality graph Which is the equation of the given line? A. x = –3 B. x = 3 C. y = –3 D. y = –3x
the only one that slants is D but it don't think its ur answer.
is there a none of the above answer choice?
no
thats weird i double checked my self and its doesn't show any of them are the answer... https://www.desmos.com/calculator (just enter in ur equations)
correct choice is not on the list
(-1,5) x1 = -1 and y1 = 5 (1,-3) x2 = 1 and y2 = -3 slope(m) = (y2 - y1) / (x2 - x1) slope(m) = (-3-5) / (1 - (-1) slope(m) = -8/2 slope(m) = -4 y = mx + b y = mx + b (-1,5) x = -1 and y = 5 (1,-3) x = 1 and y = -3 slope(m) = -4 slope(m) = -4 now we sub now we sub 5 = -4(-1) + b -3 = -4(1) + b 5 = 4 + b -3 = -4 + b 5 - 4 = b -3 + 4 = b 1 = b 1 = b as you can see, either set of points will give you the same answer.. your equation is : y = -4x + 1
