Hot dogs and Hamburgers:
1.)
The caterer for your class picnic charges $1 for each hotdog and $2 for each hamburger. You have $48 to spend. Write a model that shows the different numbers of hot dogs and hamburgers that you could purchase...
2.) Airplane landing: An Airplane's altitude is 100 feet as it is descending for a landing on a runway whose touchdown point is 5000 feet away. Let the x-axis represent the distance on the ground and the y-axis represent the airplane's altitude.
WHAT IS THE SLOPE OF THE AIRPLANE'S DESCENT????
3.) WRITE AN EQUATION of the line that follows the path of the airplane's descent.

Can't help. You will need to post one question at a time. Besides, we don't do homework for you. We help, not giving out answers sorry.
1. d+2h=48
2. So when the plane starts to descend at 100 feet, its at 0 on the X axis, so your point is (0, 100). It's touchdown point is 5000 feet away, so it will be at 5000 on the x axis and 0 on the y axis, so your point is (5000, 0). Now you have two points so you can find the slope using the slope formula, (y2-y1) / (x2-x1), so that would be (0-100) / (5000-0), which gives you -100/5000, or -1/50. The y intercept is 100 because that's what y was when x was 0. Now you have the slope and the y intercept, so go ahead and put in into slope-intercept form, y=mX-b when m=the slope and b=the y intercept, so you have
y=-1/50x+100. Hope I helped!!!!!
