Answer:

Explanation:
To convert this equation in standard form to slope-intercept form, we have to solve for y:
6x + 15y = -75
↓ subtract 6x from both sides
15y = -6x - 75
↓ divide both sides by 15

↓ simplify the fraction

From this form, we can identify the slope as -2/5 and the y-intercept as -5.
