I need help plzzzzzz

Answer 1

(1) The train travels 4 miles per gallon.

(2) The slope of the graph is
`m=(1)/(4)`

Step-by-step explanation:

(1) The miles that train travels per gallon is given by

`Miles= (800)/(200)`

Dividing, we have,

`Miles= 4`

Thus, the train travels 4 miles per gallon.

(2) To determine the slope, let us consider two points from the graph.

The coordinates are
`(0,0)` and
`(800,200)`

Thus, substituting the coordinates in the slope formula, we get,

`m=(200-0)/(800-0)`

Simplifying, we have,

`m=(200)/(800) =(1)/(4)`

Thus, the slope of the graph is
`m=(1)/(4)`
