A.y-6=-5/8(x-10)
B.y-6=-5/8 (x+10)***
C.y+6=-5/8(x+10)
D.y+10=-5/8(x+6)

2.The table shows the height of a plant as it grows. Which equation in point-slope form gives the plant's height at any time?

Time(months)2 ,4 , 6, 8
Plant height(cm)16 ,32 ,48 , 64
A.y-16=8(x-2)***
B.y-16=8x-2
C.y+16=8(x+2)
D.The relationship is nonlinear.

correct me if I'm wrong please

  1. 5/8 = (y+6)/(x+10) so I get C
    ======================
    slope = (32 - 16)/(4-2) = (y-16)/(x-2)

    16/2 = 8 = (y-16)/(x-2)
    so yes A
