Slope Intercept form
what is slope intercept form?
y = mx + b
the cube root of -1000
-10
When is the slope undefined
vertical line
x =
80% of 12

What is point slope form
y – y1 = m(x – x1)
slope intercept form quickly tells us
slope and y intercept
the square root of -4
no solution
Where is this function undefined
1/(3x)
x = 0
110% of 60

m = 4 (1,-3)
y + 3 = 2(x-1)
slope = 8 y intercept = 90
y = 8x + 90
write as a radical 8^(1/2)
square root of 8
where is this function undefined

200% increase
(2x - 6 + x^2) + (5-3x+6x^2)
7x^2 - x - 1
slope = 2 point = (5,8)
y = 2x - 2
write as an exponent
the fourth root of 5
5^(1/4)
where is this function undefined
6/(x-4)(3-x)
x = 4 and 3
