Chapter 3 - Section 3.4 - The Slope-Intercept Form of the Equation of a Line - Exercise Set - Page 253: 84

Answer

$$y = 0.265x + 27.35$$

Work Step by Step

To solve this equation, first use distributive property to get rid of the parentheses: $$y - 30.0 = 0.265(x) - 0.265(10)$$ Multiply: $$y - 30.0 = 0.265x - 2.65$$ Add $30.0$ to both sides of the equation to isolate $y$: $$y = 0.265x + 27.35$$ The equation of the line is now in slope-intercept form.
