Let f(x) = y.
y = 4x - 12
Let x = 0
y = 4(0) - 12
y = - 12
This leads to the point (0, -12).
Let y = 0.
0 = 4x - 12
1 2 = 4x
12/4 = x
3 = x
This leads to the point (3, 0).
We now graph both points and then connect each point with a straight line.
Answer:
-4
Step-by-step explanation:
Slope can be found with 
Pick two points on the graph that the line runs through
(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2
Insert the coordinates into the formula



Therefore the slope is -4
Step-by-step explanation:
3x + 2y = 9
- (3x + y = 6)
=> y = 3.
Therefore 3x + (3) = 6, 3x = 3, x = 1.
The solutions are x = 1 and y = 3.
Answer:
D. No comma because the total probability is not equal to 1.
Step-by-step explanation:
Given the distribution:

The sum of the probabilities

Therefore, the distribution is not a probability distribution because the total probability is not equal to 1.
The correct option is D.
