Answer:
y = 3x + 3
Step-by-step explanation:
y = mx + b where m= slope and b= y-intercept
the y-intercept is the point where x=0 or where the line crosses the y-axis.
This happens at (0,3) on the graph, so the y-intercept, or b, is equal to 3.
for m, slope can be defined as rise/run. So starting from a point you are given on the graph (-1,-2), count the number of spaces up you rise and how many you must go over (run) to get to the next point (0,3)
if you count, you should rise from (-1,-2) 5 spaces and move to the right (run) 1 space to get to (0,3).
rise/run = 3/1
3/1 = 3
the slope is 3.
now that you have the slope and the y-intercept, you can just plug it into the equation
y = 3x + 3
The equation used in this problem is <span>f(x)=x^4−x^3−2x−4
The factored version is F(x)=(x-2)(x+1)((x^2)+2)

Answer:
b
Step-by-step explanation:
does this help
The coordinates of D are (-3, -7)
First we need to find the coordinates of B. In order to do that we simply take the average of the two points that make up the segment for which it is the midpoint (A and C).
Average of x's
-9 + -1 = -10/2 = -5
Average of y's
-4 + 6 = 2/2 = 1
Therefore, the coordinates of B are (-5, 1).
Now we can find D by noting the E will be the average of B and D. So we can use the average equation to determine the values of D.
Average of x's
(B + D)/2 = E
(-5 + D)/2 = -4
-5 + D = -8
D = -3
Average of y's
(B + D)/2 = E
(1 + D)/2 = -3
1 + D = -6
D = -7
Now we know the coordinates of D to be (-3, -7)
