1. 13
2. 9 or 38 not really sure
3.1595
4.. 810
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108
The 6th term is 108
The slope is the factor in front of x, so slope is 9.
The y intercept is 7 (that's the point of cross the y axis, where x=0)
There are multiple definitions of "standard form" for lines, so here are the two i can think of:
9x - y = -7 (the implicit function form)
or
y-7 = 9*(x-0) (the point-slope form)
Lmk if you have questions.
When two variables varies inversely with each other, their product is always constant.
Since y = 4 when x = 4, their constant product is 16.
So when x = 2, y = 8.
