Answer: The cost of 8 hats = $60.
Step-by-step explanation:
In the given graph , the x-axis is representing the number of hats and y-axis is representing the cost of hats ( in dollars $).
To find the cost of 8 hats , just look at the x-axis and search for point x=8 on it .
Then , draw a straight line vertically passing through x=8 or just look at the dot marked above x=8 on the graph.
Then check the y-value associated with that dot or draw a horizontal line from that point , you will get y= 60
It means, the cost of 8 hats = $60.00.

Answer:
y=1/2x-5
Step-by-step explanation:
From the picture you can see that (0, -5) is a point on the function and that (2, -4) is another point. Using these you can find the slope of the function with the equation
We can substitute in the points so it looks like
or
which is the slope of the function
Now, since the y-intercept is (0, -5) on the graph, the b part in the slope-intercept form of the equation would be -5, leaving us with the equation y=1/2x-5
