Answer:

Step-by-step explanation:

(5,1) ; m = -3

Line equation: (y - y₁)= m(x - x₁)

y - 1 = -3 * (x - 5)

y - 1 = -3x + 15

3x + y = 15 + 1

3x + y = 16

Answer:

4. y = 1/2x + 3/2

Step-by-step explanation:

First, we need to change the line that's parallel into slope-intercept form.

-2x + 4y = 8

4y = 2x + 8

y = 1/2x + 2

If it's parallel, then it remains the same. So our slope is 1/2.

To find the y-intercept, you need to plug the coordinates into the equation.

y = 1/2x + b

-1 = 1/2(-5) + b

-1 = -5/2 + b

3/2 = b

y = 1/2x + 3/2

Answer:

The 4th list: Gregor, Isabelle, Juan, Karen, Hiroki.

Step-by-step explanation:

Times compared to personal best when arranged from most imporoved to least improved are:

+5.6, +3.2, 0, -5.2, -11.6

Now +5.6 is Gregors, +3.2 is Isebelle's, 0 is Jaun's, -5.2 is Karen's, and -11.6 is Hiroki's. Therefore, the list that orders runners from most improved to least improved is

Gregor, Isabelle, Juan, Karen, Hiroki
