Question: 1 / 400

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 = 2x - 3

The equation of a line in slope-intercept form is given by the formula \( y = mx + b \), where \( m \) represents the slope and \( b \) represents the y-intercept.

In this case, the desired slope is 2 and the y-intercept is -3. Plugging these values into the formula gives:

\[

y = 2x - 3

\]

This equation clearly indicates that for every unit increase in \( x \), the value of \( y \) increases by 2 (reflecting the slope of 2), and when \( x = 0 \) (the point where the line intersects the y-axis), \( y \) equals -3.

Therefore, this correctly represents a line with the specified slope and intercept.
