Writing Linear Equations in Slope-Intercept Form
The slope of the line given by y = 2x + 3
What is 2?
The inverse of (2,3)
What is (3,2)?
Find the slope of the line that passes through (-3, -2), (-3, 2)
What is undefined
y-y1=m(x-x1)
What is the equation for point-slope form?
The y-intercept for the line given by y = 7x - 9
What is -9
Inverse of the points (-3,4) (-1,1) (4, -7)
What is (4, -3) (1,-1) (-7, 4)
y2-y1 over x2-x1
What is the method of finding the slope of a line?
y = mx + b
What is slope-intercept form?
This represents the rate of change of a quantity
What is m (or slope)?
The inverse of f(x) = 3x
What f-1(x)= x/3
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?
The inverse of f(x)= 2x-7
What is f-1(x)=(x+7)/2?
Write the equation (slope-intercept form) of the line that passes through (-1, 2), (0, 5)
y = 3x + 5
(y-y_1)/(x-x_1)
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?
The inverse of f(x)=2/3 x+ 4
What is f-1(x)= 3/2 x - 6?
Write the equation in STANDARD FORM that goes through the points (2,2), (3,1)
x+y = 4
