Answer 2

To find the values of y for the given values of x, we'll use the equation y = -4 3/7x. Let's plug in each value of x and calculate the corresponding values of y:

1. x = 49: y = -4 3/7 * 49 y = -4 * 49 - 3/7 * 49 y = -196 - 3/7 * 49 y = -196 - 147/7 y = -196 - 21 y = -217

So, when x = 49, y = -217.

2. x = -2.8: y = -4 3/7 * (-2.8) y = -4 * (-2.8) - 3/7 * (-2.8) y = 11.2 + 8/7 y = 11.2 + 1 1/7 y = 12 1/7

So, when x = -2.8, y = 12 1/7.

3. x = 0.07: y = -4 3/7 * 0.07 y = -4 * 0.07 - 3/7 * 0.07 y = -0.28 - 0.03 y = -0.31

So, when x = 0.07, y = -0.31.

4. x = 57.4: y = -4 3/7 * 57.4 y = -4 * 57.4 - 3/7 * 57.4 y = -229.6 - 163/7 y = -229.6 - 23 2/7 y = -252 2/7

So, when x = 57.4, y = -252 2/7.

To summarize: y = -217 when x = 49 y = 12 1/7 when x = -2.8 y = -0.31 when x = 0.07 y = -252 2/7 when x = 57.4
