Answer: [tex]\bold{y =-\dfrac{3}{8}x-\dfrac{5}{4}}[/tex]
Step-by-step explanation:
[tex]-3x - 8y = 10\\\\.\qquad - 8y = 3x+10\qquad \rightarrow \qquad \text{added 3x to both sides}\\\\.\qquad \qquad y = \dfrac{3}{-8}x+\dfrac{10}{-8}\quad \rightarrow \quad \text{divided everything by -8}\\\\.\qquad \qquad y =-\dfrac{3}{8}x-\dfrac{5}{4}\qquad \rightarrow \quad \text{reduced the fraction}[/tex]
