Writing Linear Functions
y=mx+b
slope intercept form
m= slope
b= y-intercept
y-y1=m(x-x1) point slope form
Ex
...
Write the equation of the line that goes through (7,6) and has a slope of 1/4
...
2
...
x-(-9) y-7
m-13
answer: y-7=13(x+9)
Ex
...
Write the equation that goes through (-2,-3) and (2,5)
...
Parallel Lines: SAME SLOPE
ex
...
Perpendicular Lines: OPPOSITE RECIPROCAL SLOPE
ex
...
to y=(5/6)x-7 through (-4,-2)
x=(-4) y=(-2) m=(-6/5)
answer: y+2= -6/5(x+4)
3
...
Horizontal Lines: ZERO SLOPE
y=y1
