Answer:
B
Step-by-step explanation:
See attached image for table and graph.
Looking at Candy Lane, we can see that
1 cost 8
2 cost 16
3 cost 24
....etc
That tells us that unit rate is $8
Now, looking at graph of Best Fudge, we can see that
at x = 1, y = 3
at x = 2, y = 6
...
etc.
So we can say unit rate is $3.
Certainly, unit rate of Best Fudge is less than unit rate of Candy Lane. Answer choice B is right.
Answer:
a
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - , thus
y = - x + c ← is the partial equation
To find c substitute (- 5, 8) into the partial equation
8 = 1 + c ⇒ c = 8 - 1 = 7
y = - x + 7 ← in slope- intercept form
Multiply through by 5
5y = - x + 35 ( add x to both sides )
x + 5y = 35 ← in standard form → a
