9) In the standard co-ordinate system, which of the following points in the greatest distance from origin? A. (-4, -1) B. (-3, 3
ludmilkaskok [199]

The point with the greatest distance to the origin is given by:

B. (-3, 3).

<h3>What is the distance between two points?</h3>

Suppose that we have two points, (x_1,y_1) and (x_2,y_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The origin is given by point (0,0), hence the distance of a point (x,y) to the origin is given by:

D = sqrt(x² + y²).

Hence the distances for each point given in the problem are:

  • A. Distance = sqrt((-4)² + (-1)²) = sqrt(17).
  • B. Distance = sqrt((-3)² + (3)²) = sqrt(18).
  • C. Distance = sqrt((4)² + 0²) = sqrt(16).
  • D. Distance = sqrt((2)² + 3²) = sqrt(13).

Hence option B has the greatest distance.

1. what is the equation of a line that has an x-intercept of 2 and a y-intercept of 8
Phoenix [80]

Answer:

B

Step-by-step explanation:

x- intercept = 2  .So, Coordinate(2 , 0)

y-intercept = 8 . So, Coordinate (0, 8)

Slope = \frac{8-0}{0-2}\\\\=\frac{8}{-2}\\\\=-4

Slope y-intercept form: y = mx + b  {Here, b is y-intercept}

y = -4x + 8

nikdorinn [45]
:Jason is tossing a fair coin. He tosses the coin ten times and it lands on heads eight times. If                                           Jason tosses the coin an eleventh time, what is the probability that it will land on heads?  
Solution:
​
The probability would be ½. The result of the eleventh toss does not depend on the previous                                   
results.
