Answer:
The answer is D
Step-by-step explanation:
You can find it by expanding the equation in the form of y = mx + b :
y - 4 = 3(x + 1)
y - 4 = 3x + 3
 y = 3x + 3 + 4
 y = 3x + 7
Then, looking at the equation "b" is a y-intercept. The line that touch/passes through y-axis is called <u>y</u><u>-</u><u>i</u><u>n</u><u>t</u><u>e</u><u>r</u><u>c</u><u>e</u><u>p</u><u>t</u>. From the equation, we know that 7 is the y-intercept. 
By looking at the diagram, only Graph D is suitable for this equation because the line has touches 7 at y-axis.
 
        
             
        
        
        
Answer:
A. mean 71.33, median 86, mode 90 90 100 100, range 55
B. mean 79.41, median 36.5, mode 90, range 60
c. mean 73.16, median 2, mode 75 75 80 80, range 45
Step-by-step explanation:
mean is the average so add all numbers then divide by the number of number 
mode is the number that is often seen 
range subtract the smallest from largest or the other way around
median the middle number when lined all number from less to biggest
