Jack and nina are graphing two equations on a coordinate grid. jack has graphed the equation y = 2x.

if nina graphs y = 5x, where will her graph be in relation to the graph jack made?
a) for all x > 0 the graph will be higher.
b) for all x > 0 the graph will be lower.
c) for all x the graph will be higher.
d) for all x the graph will be lower.

ANSWER

A)For all x > 0 the graph will be higher.

EXPLANATION

Jack's graph has equation

y=2x

This graph passes through the origin and has slope 2.

Nina's graph is y=5x.

This graph also passes through the origin and has slope 5.

Since 5 is greater than 2, for all x>0, Nina's graph will be higher.

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
