write an equation in standard form for the line that has an undefined slope and passes through (-6,4)
Verdich [7]
Undefined slope is rise/0

that means it doesn't go left or right
means it is vertcal
means it is x=somethig

(x,y)
(-6,4)
x=-6 is the equation

oh, forgot about standard form

standard form is
ax+by=c

so

x+0y=-6 would be the equation in standard form

What is the value of x in the equation 1/3x − 2/3 =− 18?
Klio2033 [76]

Answer:

x = -52

Step-by-step explanation:

\frac{1}{3}x-\frac{2}{3}=-18

Let us solve for x.

\frac{1}{3}x=-18+\frac{2}{3}

\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}

\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}

\frac{1}{3}x=\frac{-54+2}{3}

\frac{1}{3}x=\frac{-52}{3}

Use cross multiplication to find the value of x.

\frac{1x}{3}=\frac{-52}{3}

3*1x=3*-52

3x=-156

Divide both sides by 3.

x = - 52
