Linear Functions Mind Map
Transcript of Linear Functions Mind Map
b is the y-intercept y - y1= m (x - x1) This can be written when the slope and the coordinates of a point on the line are known. point: (x1, y1) slope= m Example: The slope of a line is 4/7, and is passing through point (11, -5).
Written in slope-point form, the equation would be: y1= -5
x1= 11 slope: 4/7 y-y1=m(x-x1) y--5 = 4/7 (x-11) y+5 = 4/7 (x-11) [Credit: I made this one up too.] Example: The slope of a line is -5/6. The y-interecept is 3. Written in slope-interecept form, the equation would be: slope: -5/6
y-int= 3 y=mx+b y = -5/6 + 3 [Credit: I made this up alllll by myself.] *If different points on the same line are used, a different equation is written, but it still makes the same graph! Example: point: (-2,3)
equation: y-3=-4/5(x+2) point: (3,-1)
equation: y+=-4/5(x-3) To transfer from slope-point form into slope-intercept form, solve for y. Example: Slope point form equation:
y-3= 4/5 (x+2) Solve for y:
y=4/5x + 4/5 (2/1) +3
y=4/5x + 8/5 + 3/1
y=4/5x + 8/5 +15/5
y=4/5x + 23/5 Credit: http://math.about.com/od/function1/ss/Parallel-Perpendicular-or-Neither_2.htm Example: Equations y-5= -3/7 (x-2)
and y= -3/7x + 6
are parallel because they both have a slope of -3/7 Example: A line parallel to y=5x +7
could be y= -1/5x + 7 because 5 and -1/5 are negative reciprocals. Credit: http://math.about.com/od/function1/ss/Parallel-Perpendicular-or-Neither_3.htm Flip the number of the slope and change the sign Maria Yanagisawa

Mind Map LINEAR FUNCTIONS formula: m= y2-y1 x2-x1 Creates a right angle Credit: http://www.sparknotes.com/math/algebra1/writingequations/section2.rhtml General Form Ax + By + C = 0 *A is a whole number, and B and C are integers.
You can get rid of the fractions by multiplying the numbers. Example: To convert this equation, written in standard form, 2x-3y=12 into general form:
Move the 12 to the left, and do 12-12 on the right.
2x-3y-12=0 Credit: From the Pearson F&P textbook, p. 378 Examples: From slope- intercept form:
2x+3y-12=0 From Slope-point Form:
3x-5y+11=0 Credit: From Pearson F&P textbook, p.379
