Answer: Your welcome!

Explanation:

The graph of 3x-1 for the value of x from -3 to +3 is a straight line which is shown in the graph below.

Graph:

The line cuts the x-axis at (-1, 0) and cuts the y-axis at (0, -1).

To find the value of x when y = 4.5, we need to solve the equation 3x-1 = 4.5.

Subtracting 1 from both sides of the equation we get 3x = 5.5.

Dividing both sides by 3, we get x = 1.83.

To find the value of y when x = 1.3, we need to substitute the value of x in the equation 3x-1.

So, the value of y when x = 1.3 is 3(1.3)-1 = 3.9-1 = 2.9.

Therefore, the value of x when y = 4.5 is 1.83 and the value of y when x = 1.3 is 2.9. The coordinates at which the graph cuts the x-axis and y-axis are (-1, 0) and (0, -1) respectively.
