Answer:
y = 2x - 3
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given the line with equation
y = 2x - 1 ← in slope- intercept form
with slope m = 2
• Parallel lines have equal slopes , then
y = 2x + c ← is the partial equation of the parallel line
to find c , substitute the point (1, - 1 ) into the partial equation
- 1 = 2(1) + c = 2 + c ( subtract 2 from each side )
- 3 = c
y = 2x - 3 ← equation of parallel line
