Answer 1

a) m=tg45°=1

y=y0+m(x-x0)

y=6+1(x-3)

y=6+x-3

y=x+3

b) m= (½-0)/(0-¼)

m= ½/-¼ =½×(-4)=-2

y=y0+m(x-x0)

y=½-2(x-0)

y=½-2x

c) m=-6

b=0

y=mx+b

y=-6x

d) m=(-4-2)/(-8-7)=-6/15 = -2/5

y=y0+m(x-x0)

y=2-2/5 (x-7)

y= 2 -2x/5 +14/5

y=(24-2x)/5

e) m=tg120°=-tg60= -√3

b=9

y=mx+b

y= -√3x+9

f) m=-5/3

y=y0+m(x-x0)

y=-1-5/3 (x-2)

y= -1 -5x/3 +10/3

y= (-3-5x+10)/3

y=(7-5x)/3
