Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Slope is the ratio of change in y direction to change in x direction that is [tex]slope=\frac {\triangle y}{\triangle x}[/tex]
Using the co-ordinate system, change in x is 9-4=5 points
change in y=7-5=2 points
[tex]Slope=\frac {2}{5}[/tex]
Note that since slope is a ratio, it doesn't have units
Therefore, the slope is [tex]\frac{2}{5}[/tex] or 0.4 when expressed as a decimal or 40% when expressed as a percentage
