1/2
-1/2
2
-2
What does "m" stand for in the slope formula?
y axis
slope
y coordinate

What is the first step to finding the slope when given a set of coordinates?
Solve the formula
Label the coordiantes
Plug coordinates into the formula
Yell, "I don't know how to do this!"
g = 6x solve for x
x = 6 g
x = g6
x = g+6
x = g−6
y = 2x −2 solve for x
x = 2y−2
x = 2y−2
x=2y+2
x = y +2
−3x +2c = 3 solve for x
x=−33−2c
x = 6+2c
x = 6−2c
x = 33+2c
d = 3xy − y solve for x
x = 3yd−y
x = 3yd+y
x = 3yd−y
x = 3yd+y
How would you write y = 2x - 3 in function notation?
y = 2x-3
f = 2x - 3
f(x) = 2x-3
How do you read f(x)?
f x
f of x
f parenthesis x
f with an x inside parenthesis
If a question asks you to find f(2), what does that mean?
Let x = 2
Let y = 2
If f(x) = 2x + 1, what would be your first step to find f(1)?
Plug a 1 in for all the x's
Set the function equal to 1
Only plug a 1 into the left side
Only plug a 1 into the right side
If f(x) = 2x+1, what would the function look like once you substitute in a 1 to find f(1)?
f(x) = 21+1
f(1) = 2 (1) + 1
f(1) = 2x (1) + 1
If I know that f(2) = 4, what is another way I can write my answer?
2,4
(2, 4)
That is the only way to write it.
g(10) = ______
g(8) = ______
x(2) = ______
