Slope Intercept
Write an equation of the line through (-4,2) with a slope of -3.
y=-3x-10
How are the slopes of two parallel lines similar?
They are the same
What's the inverse of {(4,-10),(7,-19),(-5,17),(-3,11)}
{(-10,4),(-19,7),(17,-5),(11,-3)}
r
What's a negative correlation mean?
all the points in a scatter plot tend to have a negative slope
In the equation y=mx+b, what does b represent?
b is the y intercept or where the line crosses the y axis.
How do I find the slope of a perpendicular line to the line y=3x+5?
You take the opposite reciprocal of the slope, so you would get -1/3
How do you say f-1(x)?
The inverse of f of x
f of x inverse

1/6
What's the third step in finding the inverse of an equation?
Solve the equation for y
What do you do after you've found your linear regression?
What is my fiance's name?
Traven
Find the equation of the line through (100,160) and (500,680). Then estimate when x=750
y=1.3x+30,1005
Find the equation of the line that's parallel to y=4x-9 and goes through the point (2,-3).
y=4x-11
Find the inverse of f(x)=4x-8
f-1(x)=(x+8)/4
After inputting my data into the State edit, how do I find my linear regression?
You hit Stat, Calc and go down to LinReg(ax+b). Press enter and find the equation.

Write an equation for the line that passes through the origin and (2,4)
y=2x
Write the equation of the line perpendicular to y=-2x+5 and through the point (1,4)
y=1/2x+7/2
Find the inverse of C(x)=5/9(x-32)
C-1(x)=9/5x+32
If I have graphed my linear regression and my points, how do I estimate a value using my calculator?
You would hit 2nd Trace and choose value. Type your value in for x
