Answer:

y=4x+1

Step-by-step explanation:

1. Find the slope using the slope formula and the ordered pairs.

Slope formula: y2-y1/x2-x1

3--1/1-0

= 3+1/1-0

= 4/1

Slope=4

2. Use the slope and one of the ordered pairs and put them into point-slope form

Point-slope: y-y1=m(x-x1)

M represents the slope and x1 and y1 represent the values in the ordered pair.

Let's use the pair (0,-1)

y+1=4(x-0)

3. Distribute 4 to x and 0 and subtract 1 from both sides to simplify the equation.

y+1=4x

y=4x-1

4. The equation is y=4x-1, which is written in y=mx+b form.

What is the coordinate of point P on the line segment AB that is 3/4 of the distance from A to B for A(2,5) and B(6,9)?
Brut [27]

Answer:

p  is (3.71, 6.71)

Step-by-step explanation:

Given that p is at the distance of 3/4 from A to B

it mean that point p divides the line AB into 3:4 ratio.

and

if there are two points (x1,y1) and (x2,y22) which is divided by point p in the ratio m:n then

coordinates of point p (x,y) is given

p (x = (n*x1+m*x2)/m+n , y = (n*y1+m*y2)/m+n )

________________________________________________

Given the points AB

A(2,5)

B(6,9)

m:n = 3:4

thus,

p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )

p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )

p (x = (26/7 , y = 47/7 )

P ( x = 3.71, y = 6.71)

Thus, coordinates of point p  is (3.71, 6.71) which is  at  3/4 of the distance from A to B for A(2,5) and B(6,9)/

At a​ school, 102 students play at least one sport. This is 40​% of the students at the school. How many students are at the​ sc
viktelen [127]
To get from 40% to 100%, divide by 2 and multiply by 5.
I.e. 40/2 = 20
20 x 5 = 100%

Do the exact same for 102
102/2 = 51
51 x 5 = 255 students
