Answer:

Explanation:

So, first you will want to put it in Slope-intercept form

y=mx+b

but since there is no y you will have to move the x to the 3x by subtracting to get 2x, and then you will have 2x=-6 which when you divide both sides by 2 you will get x=-3 my teacher taught me a trick where H0Y is for when you are only given a y and no x and VUX is for when you are given only a x and no y

so you would get x=-3 which would be a vertical line (up and down line) at -3 on a graph (I listed the tricks my teacher taught me below)

Horizontal (horizontal line)

0=slope (zero slope)

Y=(your answer)

Vertical (vertical line)

Undefined slope

X=(your answer)
