Question

The equation y = negative StartFraction 1 Over 20 EndFraction x + 10 represents the gallons of gasoline that remain in Michelle’s car after she drives x miles. Which graph represents this equation?

Answer 1

We have the equation:

`y=(1)/(10)x`

And we have to graph it.

As the y-intercept is 0, the line goes through the origin (0,0).

Another point of the line is, when x=10, y=1, so the point (10,1) belongs to the line.

With 2 points known we can draw the line in the graph:
