Write an equation of the line that passes through (18, 2) and is parallel to the line 3y−x=−12

First isolate the "y" in the equation.

2y - x = -12 Add x on both sides

2y - x + x = -12 + x

2y = -12 + x   Divide 2 on both sides to get "y" by itself

y = \frac{-12 +x}{2}

y = -6 + \frac{x}{2}

Your slope is \frac{1}{2}.

For the equation of the line to be parallel to the given equation, the slopes have to be the same. So the parallel line's slope is also \frac{1}{2}

y = mx + b

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

To find "b", you plug in the point (18,2) into the equation

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

2 = \frac{1}{2}(18) + b

2 = 9 + b Subtract 9 on both sides

2 - 9 = 9 - 9 + b

-7 = b


Your equation is:

y =\frac{1}{2}x - 7

What is the equation of this line in slope-intercept form (-1,5) and (1,-3)?
Harrizon [31]
Slope intercept means
y=mx+c
the slope of the line is m=(y2-y1)/(x2-x1)=(-3-5)/(1+1)= -4
the equation of the line is
y-5 = -4(x+1)
4x+y-1=0
changing the equation into slope intercept form
y= -4x+1
