False.
If (x+1) is a factor of the polynomial, the polynomial must be divisible by (x+1).
In other words, when you divide the polynomial by (x+1), the remainder should be 0.
In this case, however, the remainder is 24.
Answer:

Step-by-step explanation:
30/2=15
24/2=12
15/3=5
12/3=4
4/5
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
