Number 17 please. Need to know how to take the info and make it into a slope intercept equation.
Oksi-84 [34.3K]

Answer:

y = 5x -15

Step-by-step explanation:

slope/y-int from = y =mx+b

slope = y2-y1/x2-x2

slope = 0--15 / 3-0

slope = 15 / 3

slope = 5

y-int = -15

y = 5x-15

HELP If you apply these changes to the linear parent function , f(x)-=x what is the equation of the new function vertically comp
Aleksandr [31]

Answer:

transformed function, g (x) = (1/5)(-x)+7

Step-by-step explanation:

Assuming

f (x) = -x           (and not f(x)-=x)

To compress/expand, we apply

g (x) = a*f(bx-k)+h

where

a=vertical stretch factor, a= 1/5 for compression (to stretch 5 times, a=5)

b=horizontal compression factor (=1 i this case)

h=vertical translation (=7)

k=horizontal translation (=0)

So the transformed function,

g (x) = (1/5)(-x)+7

What is the x and y intercept
Olenka [21]
Look carefully at the point where the 2 lines intersect.  From that point, look straight down to the x-axis; you'll see that the x-value there is 50.  Similarly,
starting at the intersection, look straight left to the y-axis; the y-value there is 11.

Thus, the coordinates of the intersection (i. e., the solution) are found in (50,11).
