Answer:
-6
Step-by-step explanation:
The slope of the line is ...
m = (y2 -y1)/(x2 -x1)
m = (-4.5 -3)/(-3 -(-8)) = -7.5/5 = -1.5
Then the point-slope equation can be written as ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -3 = -1.5(x +8) . . . equation of the line through the given points.
We want the value of x for y = 0, so ...
-3 = -1.5(x +8)
2 = x +8 . . . . . . . divide by -1.5
-6 = x . . . . . . subtract 8
The x-intercept of this linear function is x = -6.

<em>Additional comment</em>
In slope-intercept form, the function can be written as ...
g(x) = -1.5x -9
If you do the math you'll get 3/4 of the bag is dirt.
Let x be the number of days and y represent miles driven.
Since it costs 25 per day, you multiply 25 by x.
25x
10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y
25x+.1y
The answer is <span>a.) 25x + 0.1y</span>.
