Let's solve each problem step by step.
We are given equations in the
slope-intercept form:
$$
y = mx + b
$$
Where:
- $ m $ is the
slope
- $ b $ is the
y-intercept
So, for each equation, we just need to identify:
- The coefficient of $ x $ → that’s the
slope
- The constant term (when $ x = 0 $) → that’s the
y-intercept

- Slope: $ \frac{4}{5} $
- y-intercept: $ -1 $
✔ Answer: Slope: $ \frac{4}{5} $, y-intercept: $ -1 $
---
9. $ y = -\frac{8}{3}x + 4 $
- Slope: $ -\frac{8}{3} $
- y-intercept: $ 4 $
✔ Answer: Slope: $ -\frac{8}{3} $, y-intercept: $ 4 $
---
10. $ y = -4x + \frac{1}{4} $
- Slope: $ -4 $
- y-intercept: $ \frac{1}{4} $
✔ Answer: Slope: $ -4 $, y-intercept: $ \frac{1}{4} $
