Answer:
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(a). (- 3, 7)
(- 1, 13)
m = [tex]\frac{13-7}{-1+3}[/tex] = 3
y - 13 = 3(x - 1)
y = 3x + 10
(b). (12, 10)
(8, 12)
m = - [tex]\frac{1}{2}[/tex]
y - 12 = - [tex]\frac{1}{2}[/tex] (x - 8)
y = - [tex]\frac{1}{2}[/tex] x + 16
Now is your turn. You can do it!!
