Question

The table shows the number of gallons of paint Mrs. Brown used to paint the of rooms in her house. Find the slope of the line

Answer 1

The slope is
`(3)/(2)` or
`1.5`

Explanation:

The slope formula:
`(y2-y1)/(x2-x1)`

Now, in this case, when you get tables, you could choose two coordinates.

So, for instance, you chose the coordinates: (2,3) and (6,9)

Since we have the two coordinates, we now could solve for the slope.

Substituting and finding the slope:

1)
`m =(9-3)/(6-2) \\`

2)
`m = (6)/(4) = (3)/(2)`

3)
`m = (3)/(2)` or
`1.5`
