Chapter 3 - Section 3.4 - The Slope-Intercept Form of the Equation of a Line - Exercise Set - Page 253: 83

Answer

$$y = -\frac{3}{2}x + 3$$

Work Step by Step

To put this equation into slope-intercept form, we must solve for $y$ by subtracting $3$ from each side of the equation: $$y = -\frac{3}{2}(x - 4) - 3$$ Let's use distributive property to simplify the equation: $$y = -\frac{3}{2}x + \frac{12}{2} - 3$$ Simplify the fraction: $$y = -\frac{3}{2}x + 6 - 3$$ Group like terms: $$y = -\frac{3}{2}x + (6 - 3)$$ Combine like terms: $$y = -\frac{3}{2}x + 3$$
