2) line DE is a tangent line which only touches the circle at exactly one spot. We need something that cuts the circle in 2 spots for it to be a secant line. This can also be crossed off the list.

3) segment HG is a chord, which is fairly close to a secant line, but it must extend infinitely in both directions. In other words, it needs to be a line instead of a line segment. This is crossed off the list.

4) line CD is a secant line. It is a geometric line in that it goes on forever in both directions (it's not a segment, and not a ray either). Also, this line crosses the circle at 2 points, which contrasts it from a tangent line. This is the answer we want.

Find the slope of the line that goes through the given points (-1, 4), (5, 4)

Temka [501]

The formula would be y₂-y₁ ÷ x₂-x₁
-1 :x₁
4 : y₁
4-4/5-(-1) = 0 
5 : x₂
4 : y₂

0 is the slope

Part a: There is an 11% decrease in the price

Part b: There is an 8% decrease in the price

Part c: There is an 8% increase in the price

Part d: There is an 11% increase in the price

Part a:

Original price = $63

New price = $56.07

Change in price = 56.07-63 = - 6.93

Percentage change in price = Change in price/Original price*100

= -6.93/63*100

= - 0.11*100 = 11% decrease in price

Part b:

Original price = $37.50

New price = $34.50

Change in price = 34.5-37.5 = - 3

Percentage change in price = Change in price/Original price*100

= -3/37.5*100

= - 0.08*100 = 8% decrease in price

Part c:

Original price = $12.25

New price = $13.23

Change in price = 13.23-12.25 = 0.98

Percentage change in price = Change in price/Original price*100

= 0.98/12.25*100

= 0.08*100 = 8% increase in price

Part d:

Original price = $98

New price = $108.78

Change in price = 108.78-98 = 10.78

Percentage change in price = Change in price/Original price*100

= 10.78/98*100

= 0.11*100 = 11% increase in price
