Answer:

no, no, yes, no

Step-by-step explanation:

3x + 7y = 17

1. 3(5) + 7(3) = 17 ---> 15 + 21 = 17 (false)

2. 3(-8) + 7(-2) = 17 ---> -27 + -14 = 17 (false)

3. 3(-6) + 7(5) = 17 ---> -18 + 35 17 (true)

4. 3(8) + 7(-1) = 17 ---> 18 + -7 = 11 (false)

Determine whether the graphs of y =-9x+12 and y=1/3x-12 are parallel, perpendicular, coincident

notka56 [123]

1) graphs y = -9x + 12 and y = 1/3x - 12 are not coincident.

2) The graphs are not parallel, because the angular coefficients are not equal

3) The condition of perpendicularity:

$k_1\cdot k_2=-1$ , where $k_1=-9;~~~ k_2=\frac{1}{3}$

$(-9)\cdot\frac{1}{3}=-3\ne -1$ - not perpendicular
