Subtract 9x from both sides: 
3x-17-9x=9x+7-9x

Now we have: 
-6x-17=7


Add 17 to both sides: 
-6x-17+17=7+17


Now we have:
-6x=24


Divide both sides by -6 to isolate x: 
x=-4

1. Write an equation in point-slope form for the line through the given point with the given slope.
ElenaW [278]

Answer: y + 2 = \frac{-1}{2} ( x - 4 )

Step-by-step explanation:

The equation of a line in point - slope form is given as ;

y - y_{1} = m (x -  x_{1})

x_{1} = 4

y_{1} = -2

m = \frac{-1}{2}

Substitute the values into the equation , we have

y - (-2) = \frac{-1}{2}( x - 4 )

y + 2 = \frac{-1}{2} ( x - 4 )

Which could be written as :

y + 2 = y + 2 = \frac{-1}{2} x + 2
