Answer:
5 <= y <= 85
Step-by-step explanation:
Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)
The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).
Using the function given, if you input 8 as the x value, you get
85 = 10(8) + 5
So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.

Answer:
y = 3/2x -10
Step-by-step explanation:
The point-slope equation can be written ...
y = m(x -h) +k . . . . . for a line with slope m through point (h, k)
Using the given values, this is ...
y = (3/2)(x -6) -1 = 3/2x -9 -1
y = 3/2x -10 . . . . . slope-intercept equation
