Answer:
Step-by-step explanation:
a) (5,5) ; (10,6); slope = 1/5
(x1,y2); (x2,y2)
y-y1 = m (x-x1)
[tex]y-5=\frac{1}{5}*(x-5)\\\\y-5=\frac{1}{5}*x-\frac{1}{5}*5\\\\y-5=\frac{1}{5}x-1\\y=\frac{1}{5}x-1+5\\\\y=\frac{1}{5}x+4[/tex]
d) (√2,7) ; (√2,-7)
(x1,y1) ; (x2,y2)
[tex]slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-7-7}{\sqrt{2}-\sqrt{2}}\\\\=\frac{-14}{0}=0[/tex]
Equation: y =7 or y = -7
