What is the equation of the line that is parallel to y = 2x + 3 and passes through the point (1, 7)?
Answer: A
Parallel lines have the same slope. The slope of the given line is m=2.
The new line also has a slope of 2 and passes through (1, 7).
Using the point-slope form y - y₁ = m(x - x₁):
y - 7 = 2(x - 1)
y - 7 = 2x - 2
y = 2x + 5
