Answer:
![slope = (8)/(5) = (16)/(10) = 1.6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/cjzcqfv6b4y8upi8wpccb6i2gx5mvr90t0.png)
Explanation:
In order to calculate the slope of a line, you need twp points. So our goal is to find two points that belong to the line via the graph. Be careful : Although you can choose two points arbitrarily, find those whose coordinates are "clear" (integers)
A(1,4)
B(-4,-4)
![slope = (difference \: in \: y)/(difference \: in \: x ) = (( - 4) - (4))/(( - 4) - (1)) = ( - 4 - 4)/( - 4 - 1) = ( - 8)/( - 5) = (8)/(5)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fdfltbihnui0fvyr9p5uf6c2kttj80mbbq.png)
