Step-by-step explanation:
Slope is Rise/Run
The change in y-values is the Rise. The line goes down from left to right here, so it is negative.
The Run is the change in x-values.
Here, for every 2 units of change in x, the y changes by 4, negative.

Answer:
60 boys
Step-by-step explanation:
boys : girls = 3 : 5
Total number of people = 160
Let y = common factor:
Therefore, 3y + 5y = 160
⇒ 8y = 160
⇒ y = 160 ÷ 8 = 20
Boys = 3y = 3 x 20 = 60
Girls = 5y = 5 x 20 = 100
So there are 60 boys and 100 girls
