Standard Form
How do you find the y intercept in standard form?
Rewrite the formula in slope-intercept form and find "b"
What is the slope-intercept equation?
y = mx + b
Find the y intercept 3x + 12y = 12
y intercept = 1
What is the first step in converting this equation from standard to slope intercept form? 3x-7y=14
Subtract the 3x from both sides
5x + 2y = 10
y intercept = 5
2x + 5y = 20
y = -2/5x + 4
Find the y intercept 6x + 3y = 18
y intercept = 6
Bears have four paws, how many total claws do most bears have?
20
4x + 8y = 16
y intercept = 2
Is this a function and why?
Inputs: 5, 6, 3, 1, 7, 4, 5
Outputs: 3, 6, 1, 8, 9, 0, 2
No, because 5 has more than one output.
What is the slope of the line x=2/3?
Undefined
Write the equation in slope intercept form given Slope = -7 y intercept = -3
y = -7x - 3
7x + 3y = 21
y intercept = 7
