Let the number be x.

1st number = x
2nd number = x + 2
3rd number = x + 4

x + x + 2 + x + 4 = -9
3x + 6 = -9
3x = -15
x = -5

1st number = x = -5
2nd number = x + 2 = -3
3rd number = x + 4 = -1

Answer: The numbers are -1, -3, and -5

Use the graph to find the

Dmitry [639]

The y intercept is 2, because that is the value of y when it crosses the y axis.

Since the line is pointing down, it has a negative slope, and since the y value goes down 2 for every 3 x values, the slope is -2/3. You should always right the slope in rise/run form, or change in y/change in x.

Finally, write the equation in the form of y=mx+b, where m is the slope and b is the y intercept. This means the equation of the line is y=-2/3x+2.
