What is the equation of the following line ? (15,3) (0,0)

y = 1/5x

Step-by-step explanation:

Plot the points.

We connect them to make a line.

line equation:

y = mx + b

First, we find the slope of the line.

Two points are already given.

(15,3) (0,0)

Slope formula:

m = y₂ - y₁ / x₂ - x₁

m = 0 - 3 / 0 - 15

m = -3 / -15

m = 1/5

If we use that slope on the graph.

We can already see the y-intercept (even without a graph).

It passes at point 0.

So the equation of the line is:

y = 1/5x

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
