We have that
an=10 * 5n---------------> an=50*n

then

for n=1
a1=50*1=50

for n=2
a2=50*2=100

for n=3
a3=50*3=150

for n=4
a4=50*4=200

the answer is
the first four terms are [50,100,150,200]

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3

MAXImum [283]

Answer:

The correct option is C).

Figure show the line with slope of -1/2 and a y-intercept of 3

Step-by-step explanation:

The equation of line is given by y=mx+c.

Where m is slope and c is y-intercept.

Given that line has slope

m= $\frac{-1}{2}$ and c=3

Thus equation of line will be

y=mx+c.

y= $\frac{-1}{2}x+3$

To plot the line we need at least two points

Take x=0

y= $\frac{-1}{2}x+3$

y= $\frac{-1}{2}0+3$

y=3

The required point is A(0,4)

Take x=2

y= $\frac{-1}{2}2+3$

y=2

The required point is B(2,2)

Using this points to graph the given equation of line

Figure show the line with a slope of -1/2 and a y-intercept of 3

The correct option is C).
