Quizplus · Accepted Answer

To find the slope and y-intercept, the equation needs to be in slope-intercept form, $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. Starting with $7x - 9y = 8$, we solve for $y$: $-9y = -7x + 8$, then $y = \frac{7}{9}x - \frac{8}{9}$. Thus, the slope is $\frac{7}{9}$ and the y-intercept is $-\frac{8}{9}$.
