Answer:
y = x + 2
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 )
y = x is in this form
with slope m = 1 and c = 0
• Parallel lines have equal slopes, thus
y = x + c ← is the partial equation of the parallel line
To find c substitute (2, 4) into the partial equation
4 = 2 + c ⇒ c = 4 - 2 = 2
y = x + 2 ← equation of parallel line
