Answer:
The slope of the line is -2
Step-by-step explanation:
<em>The rule of the slope of a line is</em>:
, where
and
are two points on the line
<em>Let us find the slope using the rule above</em>
∵ The line passes through points (3, -7) and (-1 , 1)
∴
= 3 and
= -1
∴
= -7 and
= 1
<em>Substitute these values in the rule above to find m</em>
∴ 
∴ The slope of the line that passes through the given points is -2
The answer should be E.

Simple Interest , I = PRT/100
Where P = Principal, R = Rate, T = Time in years
Time, T = (100*I)/(P*R)
T = 100* 84 / (600 * 7) Use your calculator
T = 2
Time is 2 years.
Answer:
C
Step-by-step explanation:
the domain is the set of numbers that can be x values. in this case, the equation is linear so any number you plug in for x will give you a y value
