Writing Linear Equations in Slope-Intercept Form
The slope of the line given by y = 2x + 3
What is 2?
The x-coordinate of a point where a graph crosses the y-axis
What is a y-intercept?
Find the slope of the line that passes through (-3, -2), (-3, 2)
What is undefined
The y-intercept for the line given by y = 7x - 9
What is -9
Write an equation of the line that passes through the given point and is parallel to the graph of the given equation. (2, -1); y = 5x - 2 (slope-intercept form)
What is y = 5x - 11
The buttons we click to ENTER data into the calculator
Stat -> EDIT
y = mx + b
What is slope-intercept form?
This represents the rate of change of a quantity
What is m (or slope)?
Determine whether the graphs of the two equations are parallel, perpendicular, or neither. y = 6x + 2
18x - 3y = 15
What is parallel
Write the equation of the line that goes through (0, 0), (3, 3) in POINT SLOPE FORM
y-3 = 1(x - 3)
Ax +By = C
What is standard form?
This is the initial amount of a quantity
What is b?
Write an equation of the line that passes through the given point and is PERPENDICULAR to the graph of the given equation. (in slope-intercept form) (0, -5); y = 9x
What is y = -1/9 x - 5?
Write the equation (slope-intercept form) of the line that passes through (-1, 2), (0, 5)
y = 3x + 5
The regression we use to find the line of best fit
What is 4. LinReg (ax + b)
y2-y1/x2-x1
What is the slope formula?
The first step in converting from point-slope to slope-intercept form
What is distributing the "m" OR adding the y1?
Write the equation in STANDARD FORM that goes through the points (2,2), (3,1)
x+y = 4
The value that represents rate of change from the linear regression
What is the 'a' value?
The formula your calculator uses for linear regressions
What is y = ax + b?
