Step-by-step explanation:
let eqn be y - y1 = m(x - x1)
m = (9 - 1)/(-3 - (-7))
m = 2
sub (-7, 1):
y - 1 = 2(x + 7)
therefore, the equation is y - 1 = 2(x + 7)

1st step is to put the numbers from smallest to biggest. Once you do that cross one out on the left, then the right, then the left, then the right and so on. Sometimes there will be 2 numbers left, so you add them up and subtract by two. If you need further help ask! :)
Please state the options here in the comment section
1×1=1
2×2=4
3×3=9
4×4=16
5×5=25
20 does not not split up evenly like the examples above.
