Answer:
Step-by-step explanation:
The question is asking you to graph the equations.
The equations are in slope intercept form so y=mx+b
M is the slope and b is the y-intercept
First draw the y & x axis and label/number them
The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis
The slope is 2/5 and you use rise/run to continue the slope.
you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)
For the second equation, you have to turn it into slope intercept form.
You should get y=2/3x+3
You graph this equation the same as you did the first one.
Answer:
The index of refraction of the second medium is higher.
Step-by-step explanation:
Answer:
(a) The slope of f(x) is greater than the slope of g(x)
(b) f(x) has a greater y intercept
Step-by-step explanation:
Given


Solving (a): Compare the slopes
The slope (m) of f(x) is calculated as;

This gives:


Substitute values for f(0) and f(1)



The slope of g(x) can be gotten using the following comparison


So:



Solving (b): Compare the y intercept
y intercept is when 
From the table of f(x)

From the equation of g(x)
