Question 1: Line AB contains points A (0, 1) and B (1, 5). The slope of line AB is...? −4 negative 1 over 4 1 over 4 4

Line AB contains points A (0, 1) and B (1, 5). The slope of line AB is

−4
negative 1 over 4
1 over 4
4

Answer 1

The slope of line AB is 4.

Explanation:

Use the formula for slope.

`m = (color(red)(y_1) - color(blue)(y_2))/(color(red)(x_1) - color(blue)(x_2))`

In this case, the two points are `(color(red)0, color(red)1)` and `(color(blue)1, color(blue)5)`. Substituting the values:

`m = (color(red)1 - color(blue)5)/(color(red)0 - color(blue)1)`

`m = (-4)/-1`

`m = 4`

`therefore` the slope of line `AB` is `4`.
