βQ.Which of the ordered pairs is a solution of the following equation?β
-3x - y = 6
(1) only (-4, 4) (2) only (-3, 3) (3) both (4) neither
```
- slope
increase in vertical / increase in horizontal
= slope
= πΊ(delta) x / πΊ(delta) y
= change in x / change in y
higher the slope means the steeper it is
