So, the point three-fifths of the way from
on the number line.
To find a point that is three-fifths of the way from
, you can use the following formula:
![\[ \text{Midpoint} = (a + b)/(2) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/q9h21an31op4ewp4r5knihvsqgqo2xzw0u.png)
In this case,
is the starting point
,
is the ending point
, and we want a point that is three-fifths of the way from
. The formula becomes:
![\[ \text{Point} = a + (3)/(5)(b - a) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/3iz6pk50a0o0t5gkaoo6dkl4r74skt681m.png)
Substitute the values:
![\[ \text{Point} = -3 + (3)/(5)(3 - (-3)) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/ajzuu7geyfskwl62gk2d3z0wt5zu7qrdf8.png)
![\[ \text{Point} = -3 + (3)/(5)(6) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/io5k49ymm3pvxfdavdquz5um33wkt3wow1.png)
![\[ \text{Point} = -3 + (18)/(5) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/2pw0k1l104hyhjqq58rxb27wvdx8vjsv5s.png)
To make the denominators the same:
![\[ \text{Point} = (-15)/(5) + (18)/(5) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/csrhjetex4kvks4h9dkv4el03p7nsd72qz.png)
![\[ \text{Point} = (3)/(5) \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/pntsjemnyy8x25t03c84ctjr84kofj2uos.png)
