Answer 1

1. m=(5-3)/(7-2)=2/5
y-y1=m(x-x1)
y-3=2/5(x-2)
5(y-3)=2(x-2)
5y-15=2x-4
5y-2x-11=0

2. m=(0-(-5))/(2-(-3))=5/5=1
y-y1=m(x-x1)
y-0=1(x-2)
y=x-2

3. m=(-8-2)/(3-0)=-10/3
y-y1=m(x-x1)
y-2=-10/3(x-0)
3(y-2)=-10x
3y+10x-6=0

4. m=(4-2)/(7-(-7))=2/14=1/7
y-y1=m(x-x1)
y-4=1/7(x-7)
7(y-4)=x-7
7y-28=x-7
7y-x+21=0

5. m=(6-0)/(0-11)=6/-11=-6/11
y-y1=m(x-x1)
y-6=-6/11(x-0)
11(y-6)=-6x
11y-66=-6x
6x+11y-66=0
