Answer: m = -2
Step-by-step explanation: Using our slope formula, we take the second y minus the first y which in this case is 12 - 8 over our second x minus our first x which in this case is 2 - 4.
So 12 - 8 is 4 and 2 - 4 is -2. So we have 4/-2 which can be simplified to -2.
The variable that's used to represent slope is <em>m.</em>
So we would say m = -2.

Answer:
C
Step-by-step explanation:
If Ian has $25 in his piggy bank, and he can save $12 a week the equation will be
$25+($12x)=$85 (where x is the number of weeks)
85-12=$73
$73=$12x
x=<span>6.08333333333
Round up
It will take 7 weeks
