The equation of a parallel line is y = 2x + 5.
Solution:
Given equation of a line is y = 2x - 3.
Slope of the line
= 2
If two lines are parallel, then the slope of their lines are equal.


y-intercept of the parallel line = 5
That is b = 5.
Equation of a parallel line:
y = mx + b
y = 2x + 5
Hence the equation of a parallel line is y = 2x + 5.
