Answer:

The correct number is +3.5

Step-by-step explanation:

AB is the distance from A to B. It is headed to the right, as the numbers increase. So the calculation should be (Final - Initial), or (4.5 - 1) = 3.5

Answer:

AB = 3.5 cm

Step-by-step explanation:

The error was the 2 numbers being switched. Instead of 1 - 4.5, the correct calculation should be 4.5 - 1 which equals 3.5

What is the slope of the line graphed on the coordinate plane? A graph with a line running through coordinates (0, 6) and coordi

<h2>Answer</h2>

The slope of the line is -8

<h2>Explanation </h2>

To find the slope of our line we are going to use the slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

where

$m$ is the slope of the line

$(x_{1},y_{1})$ are coordinates of the first point

$(x_{2},y_{2})$ are the coordinates of the second point

We know that the first point on our graph is (0, 6), so $x_{1}=0$ and $y_{1}=6$ . We also know that the second point is (1, -2), so $x_{2}=1$ and $y_{2}=-2$ . Let's replace those values in our formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{-2-6}{1-0}$

$m=\frac{-8}{1}$

$m=-8$

We can conclude that the slope of the line passing through the points (0, 6) and (1, -2) is -8.
