My name is Ann [436]

(1) The train travels 4 miles per gallon.

(2) The slope of the graph is m=\frac{1}{4}

Explanation:

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

Miles= \frac{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=\frac{200-0}{800-0}

Simplifying, we have,

m=\frac{200}{800} =\frac{1}{4}

Thus, the slope of the graph is m=\frac{1}{4}
