Final answer:
The equation 5x + 5y = 15 can be written in slope-intercept form as y = -x + 3.
Step-by-step explanation:
The given equation is 5x + 5y = 15. To write this equation in slope-intercept form, we need to isolate y on one side. Start by subtracting 5x from both sides, we get 5y = -5x + 15. Then divide both sides by 5 to solve for y, we have y = -x + 3. Therefore, the equation in slope-intercept form is y = -x + 3.
