Answer: -2.5 students per year

Step-by-step explanation: Since there is a 6 year difference and the y values decrease by intervals of 15, from the point between '00 and '04 (which is '02) to '08, y decreases by one interval or 15, so the answer is -15/6, or -2.5.

A radio is being discounted 20%. If the sale price is $51.44, what was the original price of the radio? A. $12.86, B. 64.30, C.
katrin2010 [14]
The equation for decreasing a price by 20% is 
original price x 0.8 = sale price

Here, we can fill in the sale price so
original price x 0.8 = 51.44

This can be rearranged to show:
51.44 ÷ 0.8 = original price

So the original price was $64.30

Answer = B - $64.30

Which of the following point-slope form equations could be produced with the points (4, 5) and (-3, -5)?
NikAS [45]

Answer:

<em>Equation; y = 1 3 / 7x - 5 / 7</em>

Step-by-step explanation:

First consider the slope of this equation we must derive;

Slope Formula = Rise / Run,

y2 - y1 / x2 - x1 ⇒

5 - ( - 5 ) / 4 - ( - 3 ) ⇒

10 / 7 ⇒ Slope : 1 3 / 7

So far we can formulate an equation as such;

y = 1 3 / 7 * x + b, <em>where b ⇒ y - intercept</em>

Given one of the points, substitute into this equation solving for b;

5 = 1 3 / 7 * ( 4 ) + b,

5 = 40 / 7 + b,

b = - 5 / 7

From this we can derive one point - slope from equation to be :

<em>Equation; y = 1 3 / 7x - 5 / 7</em>
