Answer:

Y=3x+2, Y= -3x-2

Step-by-step explanation:

If you need a consistent (parallel) line you must have very similar equations, with only positives and negatives being changed. If it's Y=3x+2, only the 2 is changed from negative to positive changing the lines position. If it's Y= -3x-2 then the X value is moved to a different coordinate and the -2 keeps the change.

Hope this helps and please critique what I've done if im wrong.

What is the equation of the line slope of 3 and passes through the point (-2, 3)?

elixir [45]

Answer:

$\large\boxed{y-3=3(x+2)}\qquad\text{point-slope form}\\\boxed{y=3x+9}\qquad\text{slope-intercept form}\\\boxed{3x-y=-9}\qquad\text{standard form}\\\boxed{3x-y+9=0}\qquad\text{general form}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

We have the slope m = 3 and the point (-2, 3). Substitute:

$y-3=3(x-(-2))\\\\y-3=3(x+2)$

the point-slope form

$y-3=3(x+2)$ <em>use the distributive property</em>

$y-3=3x+6$ <em>add 3 to both sides</em>

$y=3x+9$

the slope-intercept form

$y=3x+9$ <em>subtract 3x from both sides</em>

$-3x+y=9$ <em>change the signs</em>

$3x-y=-9$

the standard form

$3x-y=-9$ <em>add 9 to both sides</em>

$3x-y+9=0$

the general form
