Phoenix [80]

Answer:

The linear function is y=50x+20

The reasonable domain is 0\ hours \leq x\leq 2\ hours

Step-by-step explanation:

Let

x ----> the time in hours

y ---> the distance in miles

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem

The slope is m=50\ \frac{miles}{hour}

The y-intercept is b=20\ miles

substitute

y=50x+20

<em>Find the domain for x</em>

For y=120 miles

Find the value of x

substitute the value of y in the linear equation and solve for x

120=50x+20

50x=120-20

50x=100

x=2\ hours

therefore

The domain is the interval [0,2]

0\ hours \leq x\leq 2\ hours

DanielleElmas [232]

Answer:

y=-2x+15

Step-by-step explanation:

First, write out the equation in slope-intercept form, with what you already have:

y=-2x+b

Let "b" represent the y-intercept.

To find the y-intercept, substitute the point (6,3) in for the "x" and "y" variable of the equation and solve for "b":

3=-2(6)+b\\3=-12+b\\3+12=-12+12+b\\15=b

Therefore, your y-intercept is 15.

That means your equation is slope-intercept form <em>is</em> y=-2x+15.
