Which of the following represents the equation of a line with a slope of 2 and a y-intercept of 3?

y = 2x + 3
y = 3x + 2
y = x + 2
y = 2x - 3

The correct answer is: y = 2x + 3

The equation of a line in slope-intercept form is written as $ y = mx + b $, where $ m $ represents the slope and $ b $ represents the y-intercept. In this case, you are looking for an equation with a slope of 2 and a y-intercept of 3. By substituting the values of the slope and y-intercept into the equation form, you get $ y = 2x + 3 $. This matches the characteristics specified in the question perfectly, where the slope (2) is the coefficient of $ x $, and the constant term (3) is the y-intercept, representing the point where the line crosses the y-axis. The other options do not match this requirement: they either present a different slope or y-intercept, which does not follow the given conditions of having a slope of 2 and a y-intercept of 3. Thus, $ y = 2x + 3 $ is the correct representation of the line as described.
