Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x + 1 ← is in slope- intercept form
with slope m =
• Parallel lines have equal slopes
t =
x + c ← is the partial equation
to find c substitute (3, 1 ) into the partial equation
1 = 2 + c ⇒ c = 1 - 2 = - 1
y =
x - 1 ← equation of parallel line
(2)
y = - x is in slope- intercept form
with slope m = - 1
y = - x + c ← is the partial equation
to find c substitute (- 3, 5 ) into the partial equation
5 = 3 + c ⇒ c = 5 - 3 = 2
y = - x + 2 ← equation of parallel line
