Answer:
[tex]slope = \frac{8}{5} = \frac{16}{10} = 1.6[/tex]
Step-by-step 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)
[tex]slope = \frac{difference \: in \: y}{difference \: in \: x } = \frac{( - 4) - (4)}{( - 4) - (1)} = \frac{ - 4 - 4}{ - 4 - 1} = \frac{ - 8}{ - 5} = \frac{8}{5} [/tex]
