Explanation
- Convert the equation into slope-intercept form.
[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
What we have to do is to make the y-term as the subject of equation.
[tex]9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y[/tex]
[tex] \frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5[/tex]
From y = mx+b, the slope is 3.
Answer
[tex] \large \boxed {slope = 3}[/tex]
