Answer:

y = 2x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (4, 8)

m = \frac{8-2}{4-1} = \frac{6}{3} = 2 , then

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 2 )

2 = 2 + c ⇒ c = 2 - 2 = 0

y = 2x ← equation of line

Why do you need to find the number that is halfway between 0 and 1 and 1/2 ?
labwork [276]

Answer:

between 0 and 1: divide 1 by 2 = 0.5

between 1 and 1/2: divide 1/2 by 2 (0.25) and multiply that by 3 = 0.75

Zinaida [17]

Answer:

y=-2x+2

Step-by-step explanation:

Just follow the slope-intercept form formula-

Formula: y= mx+b

Key:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Feel free to ask if you have any questions, hope this helps!(:

Phong is rolling a number cube and flipping a coin .what is the probability that the cube will land on 4 and the coin will land
Grace [21]
Probabblity that the cube lands on 4 = 1/6
Probablity that the coin lands heads up = 1/2
Probablity of both happening = 1/2 * 1/6 = 1/12
