What is the point slope form of a line with slope -5 that contains the point (2,-1)?
Marina CMI [18]
Answer: A

Explanation:

(Y-Y1)=m(X-X1) is the base formula for point slope. The points to plug in (X1, Y1) are in this case (2,1). Plugging in those points gives you the equation of Y+1=m(X-2). Then it asks for the slope. In this equation, m = the slope. So plug in (-5) for the slope and you get Y+1=-5(X-2).

Hope this helps!

Dimitri is helping to plan the school talent show. Each performer for the talent show has 7 minutes for his or her performance,
Kaylis [27]

15 performances can be accommodated

<em><u>Solution:</u></em>

Given that,

Each performer for the talent show has 7 minutes for his or her performance

The introduction for the talent show is 25 minutes long

The entire show including the introduction, will last 130 minutes

Thus the remaining time for performances is:

Performance time = 130 minutes - 25 minutes

Performance time = 105 minutes

To find, the number of performances, divide the 105 by 7 minutes

Number\ of\ performances = \frac{105}{7} = 15

Thus 15 performances can be accommodated
