Answer:

  • Q.8:
  • use the equation [tex]y-y_1=m(x-x_1)[/tex]
  • [tex]y-(-4)=-6(x-(7))\\y+4=-6x+42\\y=-6x+38[/tex]
  • Q.9:
  • Find slope with [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
  • substitute and solve
  • [tex]slope=\frac{(1)-(-3)}{(3)-(1)} =2[/tex] then as follows
  • [tex]y-y_1=m(x-x_1)\\y-(1)=2(x-(3))\\y-1=2x-6\\y=2x-5[/tex]
  • Q.10:
  • Find slope [tex]slope=\frac{(12)-(2)}{(2)-(7)}=-2[/tex] then
  • [tex]y-y_1=m(x-x_1)\\y-(2)=-2(x-(7))\\y-2=-2x+14\\y=-2x+16[/tex]
