Answer:
Step-by-step explanation:
100,000 doubles to 200,000 in 80 years then 400,000 in 80 more years
Linear systems that have infinite solutions have the same slope and they have the same line on the graph
Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
