From the graph, we can say that the system can be represented by a linear function. A linear function has a standard form of:
y = mx + b where m is the slope and b is the y-intercept.
From the image, b would have a value of 48. The slope can be calculated as follows:
slope = ( 48 - 36 ) / (0 - 1) = -12
The equation can be written as:
y = -12x +48
or
12x + y = 48
124.95 + 7% tax = 124.95 * 1.07 = $133.70
Plus $10 = $143.70 <--- answer to part 1
Part 2
143.70 / 15 = 9.58

Step-by-step explanation:
We require to find the third side of the triangle.
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x represent the third side, then
x² + 15² = 17², that is
x² + 225 = 289 ( subtract 225 from both sides )
x² = 64 ( take the square root of both sides )
x = 
= 8
