Arrange in slope intercept form.....
2y = 2x -4
y = x - 2
So, the line would go up......crossing the y axis at -2.........hope this helps
I think u are supposed to divide like 9.70 divided by 5
(5+4+6-2)×2×2-1
(9-4)×2×2-1
5×2×2--1
10×2-1
20-1
19
The answer is 13
If R=4 the the equation would be 4+9 which equals 13.
