Final answer:
To find the equation of a line passing through the point (2, 3) with a slope of -2, we can use the point-slope form of a linear equation.
Step-by-step explanation:
To find the equation of a line passing through the point (2, 3) with a slope of -2, we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1).
Plugging in the values, we get y - 3 = -2(x - 2). Solving for y, we get y = -2x + 7.
Therefore, the equation of the line is y = -2x + 7.
