x - 4y = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 4y = 4 ( subtract x from both sides )
- 4y = - x + 4 ( divide all terms by - 4 )
y =
x - 1 ← in slope intercept form
with slope m =![\frac{1}{4}](/tpl/images/1875/7653/0d86b.png)
Parallel lines have equal slopes, thus
y =
x + c ← is the partial equation
To find c substitute (- 8, - 1) into the partial equation
- 1 = - 2 + c ⇒ c = - 1 + 2 = 1
y =
x + 1 ← equation in slope- intercept form
Multiply through by 4
4y = x + 4 ( subtract 4y from both sides )
0 = x - 4y + 4 ( subtract 4 from both sides )
- 4 = x - 4y, that is
x - 4y = - 4 ← equation in stanfard form
