Answer:
y = (-7/3)x +3
Step-by-step explanation:
The line has a negative slope (eliminating choices B and C) that is steeper than a line with a slope of -1, The only answer choice with a negative slope less than -1 is choice D.
__
The slope is the coefficient of x. It is "rise"/"run". Here, the line goes through grid points (0, 3) and (3, -4), so drops 7 units (rise=-7) for each 3 units to the right (run=3). Then the slope is rise/run = -7/3.
The line crosses the y-axis at y=3, so the slope-intercept equation is ...
y = mx + b . . . . . . . . slope = m; y-intercept = b
y = (-7/3)x +3

Answer:
I will just show you how to substitute.
Step-by-step explanation:
all you have to do is just plug f(x) into the number you want. So if you see any x's, all you gotta do is plug that number after f for x.
So an example of an equation for one of your number is:
you then want to plug the number after f for the x's. (I'm doing f(-3).
You then should get the equation above.
after that you solve.
just follow these steps and you should be fine :))
The correct question in the attached figure
case A) an=2<span>^(n-1)
for n=8
a8=2</span>^(8-1)-----> a8=2<span>^7----> a8=128
the answer case A) is
a8=128
case B) an=7
then for n=8
a8=7
the answer case B) is
a8=7
case C) an=1+(-1)</span><span>^n
for n=8
a8=1+(-1)</span><span>^8----> a8=1+1----> a8=2
the answer case C) is
a8=2
case D)an=-(-2)</span><span>^n
for n=8
a8=-(-2)</span><span>^8----> a8=-256
the answer case D) is
a8=-256</span>
