Question

Find linear models for each set of data. In what year will the two quantities be​ equal? x y 1970 67.8 1975 69.6 1980 70.5 1985 71.4 1990 72 1995 72.4 2000 74.1

Answer 1

The graph solution is defined in the attachment file please find it.

Explanation:

The first line equation:

`\to Y= 0.22x + 67.5\\\\`

The second line equation:

`\to Y= 0.15x + 75.507\\\\`

Intersection points:

`\to (114.387,92.665)\\\\`

By adding the value of the first year (1970) into the x-value that is

`\to 114.387+1970=2084.387`
