Answer:
- x = sandwiches
- y = wraps
- y = -3/4x +420
- y-intercept = 420
- m = -3/4
Step-by-step explanation:
This is a reading comprehension question. The problem statement tells you ...
"x number of sandwiches" and "y number of wraps."
You should be able to deduce that ...
x represents the number of <em>sandwiches</em>
y represents the number of <em>wraps</em>
___
The equation 3x+4y=1680 is put into slope-intercept form by solving for y.
4y = -3x +1680 . . . . . subtract 3x
y = (-3/4)x + 420 . . . .divide by 4
Comparing this to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, we see that ...
y-intercept = 420
m = -3/4
