Answer: -2.
Q2. /<span>The slope of a
line is a <span>rate of change./</span></span>
x = -1 and y = 10
x = 1 and y = 9
(10 - 9)/(-1 - 1) = -1/2
<span>Answer: A. -1/2.
</span>Q3.
y = 3.50x + 300
<span>Answer: Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.
</span>Q4.
y = mx + b
(0; 10); (2; 20)
m = (20 - 10)/(2 - 0) = 10/2 = 5
(0; 10) ⇒ b = 10
y = 5x + 10
<span>Answer: Shanna had $10 in her piggy bank and earned $5 each week in allowance.
</span>Q5. /<span>The slope of a
line is a <span>rate of change./

Answer: 150.
Answer:
x=-6, y=-8. (-6, -8).
Step-by-step explanation:
8x-5y=-8
-7x-5y=82
---------------
-(8x-5y)=-(-8)
-7x-5y=82
---------------------
-8x+5y=8
-7x-5y=82
---------------
-15x=90
x=90/-15
x=-6
8(-6)-5y=-8
-48-5y=-8
5y=-48-(-8)
5y=-48+8
5y=-40
y=-40/5
y=-8
