Answer:
x: (-5.0)
y: (0, -17.5)
Step-by-step explanation:
The x-intercept of the line is when y=0. In the table is the point (-5,0). This is the x-intercept.
To find the y-intercept, find when x=0. Write an equation for the table in y=mx + b. Find the slope between two points first.

The slope is -3.5. So the equation is
y - 7 = -3.5(x--7)
y - 7 = -3.5 (x+7)
y - 7 = -3.5x - 24.5
y = 3.5x - 17.5
Since it is in y=mx+b, b= -17.5 and this is the y-intercept.
To prove the divisibility lets expand each number first to get the complete picture of the problem
51^7 = 8.974106779 . 10^11
51^6 = 1.75962878 . 10^10
(51^7 - 51^6) = 8.974106779 . 10^11 - 1.75962878 . 10^10
= 8.798143901. 10^11

= 3.51925756. 10^10
That is the answer expressed in scientific notation
= 35192575600
Which means the divisibility is proven
