Answer:it the last one
Step-by-step explanation:
The 487 one
I don’t know if you have to use a variable or not…
F(x)=-1x-1
1) Pick 2 points on the line (i chose (-4,3) and (3,-4)
2) Find slope of the line using the 2 points. (work below)
3) Find y-intercept, which is the point where y-axis and the line cross (y-intercept is -1).
4) Place both slope and y-intercept into slope-intercept form, y=mx+b (m=slope and b=y-intercept.)
5) Change y to f(x) (meaning function of x).
Work:
3-(-4)/-4-3=3+4/-4-3=7/-7=-1
y-intercept equals -1 also.
y=mx+b
y=-1x+(-1)
y=-1x-1
f(x)=-1x-1<---Answer
The answer is F= 3/2 because there are two sandwiches cut in half, there are three children and each one ate one half, one half was left over, the number three represents the halves that were eaten and number two represents the amount of sandwiches.
Your answer is 160. Sorry about that answer above I laughed reading it hahaha.
