An ofof in - .1. (0,-1) (4,4)2. (4,3) (1,-6)

see explanation

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 = (y₂ - y₁ ) / (x₂ - x₁ )

(1)

let (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 4), then

m = =

Note the line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = x - 1 ← in slope- intercept form

(2)

let (x₁, y₁ ) = (4, 3) and (x₂, y₂ ) = (1, - 6), then

m = = = 3, hence

y = 3x + c ← is the partial equation

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

Using (4, 3), then

3 = 12 + c ⇒ c = 3 - 12 = - 9

y = 3x - 9 ← in slope- intercept form

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

i got 10.28 but that rounds up to 10.3
