The slope of the perpendicular line is the negative reciprocal of that of the given line, so is
-1/(3/5) = -5/3
Then the point-slope equation of the perpendicular line can be written as
y = (-5/3)(x -15) -5
y = (-5/3)x +20
The y-intercept of the perpendicular line is y=20.
R divided by 14+5. I didn't know where the division sign was. Remember, the work only says to write
an expression, so you don't have to answer it unless it tells you to.

This should be the answer you just add the two lengths together to come up with the total length.
Lemme know if you get it right.

(I cannot be the number line bit sorry)
When you're finding which one is greater, you can either write these out in words, or you can put them next to eachother.
In words- Olivia: Two million, three hundred and six thousand, four hundred and twenty one. (2306421)
Clayton- Two million, three hundred and two thousand, nine hundred and seventy two. (2302972)
From writing them out, you can see that Olivia's score has 'three hundred and six thousands', where as, Clayton has 'three hundred and two thousand'
Therefore, Olivia got the higher score.
Hope this helps :)
