Answer: 5
B/c 5+1= 6 and 5 times 6 is 30
The factors of 1078 are 1, 2, 7, 11, 14, 22, 49, 77, 98, 154, 539, and 1078.
Equation of a line;
y=mx+c
m=5
y=5x+c
Replacing for x and y using point (-2, -1)
-1=5(-2)+c
-1=-10+c
c=-1+10
c=9
y=5x+9
You will have to get the difference and get a common denominator but first combine the mixed number:

Then subtract the numbers
