Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.

RoseWind [281]

Answer:

$\displaystyle m = \frac{1}{5}\cdot t$

Step-by-step explanation:

<u>Proportional Model</u>

The number of miles m that Lexus can skateboard in t minutes can be modeled by:

m = kt

It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.

Substituting:

4 = k.20

Dividing by 20

$k=\frac{4}{20}$

Simplifying:

$k=\frac{1}{5}$

This produces the model

$\displaystyle m = \frac{1}{5}\cdot t$

Write in slope intercept form an equation of the line<br> (1, 2); m = -2

mr Goodwill [35]

Y = 2
X = 1
M = -2
B = ?
y=mx+b
2=-2(1)+b
2= -2 + b
+2 +2
4 = b
Therefore the equation is
y = -2x + 4
