Chapter 2 Terms and formulas

Question 1

What is the equation of a line for slope, when given two points

Answer 1

y2-y1/x2-x1

Question 2

What is the slope-intercept form equation for a line, given the slope and y-intercept ?

Answer 2

y=mx+b

Question 3

What is the point-slope form of the equation of a line, given slope (m) that passes through (x1, y1) ?

Answer 3

y-y1=mt(x-1)

Question 4

What is a Secant line?

Answer 4

A secant line to the curve is one that crosses P

Question 5

What is a Tangent line?

Answer 5

A tangent line to the curve is one that just touches at P

Question 6

What is the Averge Velocity equation?

Answer 6

(Distance traveled)/(Time elapsed)

Question 7

What is instantaneous velocity?

Answer 7

Velocity that occurs at a specific time or moment

Question 8

How do we say the limit of f(x) is L as x aproaches a?

Answer 8

lim   f(x)  = L 
x-->a

Question 9

What is a one-sided limit? How do we represent that in our equation?

Answer 9

A one sided limit is the limit as x aproaches a from one side (the left or the right, and can be represented as such…
lim f(x) =L
x–>a^-/+
