Chapter 3 - Section 3.4 - The Slope-Intercept Form of the Equation of a Line - Exercise Set - Page 253: 82


$$y = 4x + 7$$

Work Step by Step

To change the equation into slope-intercept form, we must isolate $y$. We first distribute what is in parentheses: $$y - 3 = 4x + 4$$ We now add $3$ to both sides of the equation to isolate $y$: $$y = 4x + 7$$ The equation is not in slope-intercept form.
