Answer

The equation of the line is \( y = -4x - 6 \).

Solution

To find the equation of a line that passes through a given point and has a specific slope, we can use the point-slope form of the equation of a line, which is given by: \[ y - y_1 = m(x - x_1) \] where: - \( (x_1, y_1) \) is the point the line passes through, - \( m \) is the slope of the line. In this case, the point is \( (-3, 6) \) and the slope \( m \) is -4. Let's substitute these values into the point-slope form: 1. Identify \( x_1 \) and \( y_1 \): - \( x_1 = -3 \) - \( y_1 = 6 \) 2. Substitute into the equation: \[ y - 6 = -4(x + 3) \] Now, let's simplify this equation step by step: 1. Distribute the slope on the right side: \[ y - 6 = -4x - 12 \] 2. Add 6 to both sides to solve for \( y \): \[ y = -4x - 12 + 6 \] \[ y = -4x - 6 \] Thus, the equation of the line in slope-intercept form is: \[ y = -4x - 6 \] This is the final answer.

To find the equation of a line with a given slope that passes through a specific point, you can use the point-slope form of the equation: \( y - y_1 = m(x - x_1) \), where \( m \) is the slope and \((x_1, y_1)\) is the point on the line. Plugging in your values, we get \( y - 6 = -4(x + 3) \). Simplifying this gives you \( y = -4x - 6 \). Voilà! You have the line’s equation. Now, did you know that point-slope form is super handy for graphing lines quickly? Once you have your line’s equation, you can easily plot it by starting at the point and using the slope to find other points. In this case, from \((-3, 6)\), you would go down 4 units and 1 unit to the right for every step—you'll see your line take shape in no time! A common mistake people often make when using the point-slope form is forgetting to distribute the slope correctly. Ensure you apply the slope to both components in the equation when expanding. And don't skip simplifying your equation; it makes it clearer and easier to work with! So, keep an eye on those signs and distribute carefully!
