First find out the function for the given table.
Find the slope.
m= (y2-y1)/(x2-x1)
m=(-1-(-3)) / (-1-(-2))
m=(-1+3) / (-1+2)
m=2/1
m=2
Now equation of line:
y-y1=m(x-x1)
y-(-3)=2(x-(-2))
y+3=2(x+2)
y+3=2x+4
y=2x+1
Now plot these points on the graph, we get the attached graph.
25=2,500, 278= 27800%, 2.9=290, 3.0=300, 0.67= 67
Answer is : 1.2 geometric series
<h2>
QUESTION</h2>
What is 33% of 400?
<h2>
ANSWER AND EXPLANATION</h2>
To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.
<h3>
DECIMAL</h3>
To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.

Now that you have your decimal, multiply by 400:

ANSWER = 132
<h3>
FRACTION</h3>
To change a percent into a fraction, make the percent number as the numerator(top number) and 100 as the denominator(bottom number) since fractions are out of 100.

Now that you have your fraction, multiply by 400:

ANSWER = 132
