Ok so on day 0 we know the road was 44 miles, thats our intercept.
Now if only 1 mile is added per day, then we get

Now lets plug in 35

After 35 days the length of the road was 79 miles.
Answer:
y = - 9 and x = - 2
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 2, - 9) with y- coordinate - 9, thus
y = - 9 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, - 9) with x- coordinate - 2, thus
x = - 2 ← equation of vertical line
