Final answer:
The equation in slope-intercept form is y = (1/15)x + 4/3. The slope is 1/15 and the y-intercept is 4/3.
Step-by-step explanation:
(a) To write the equation in slope-intercept form, we need to isolate y on one side of the equation. We start by adding 20 to each side: x + 20 = 15y. Then, divide each side by 15: y = (1/15)x + 20/15, which simplifies to y = (1/15)x + 4/3.
(b) In slope-intercept form, the slope is the coefficient of x, which is 1/15, and the y-intercept is the constant term, which is 4/3.
