Don't be shy about using actual parentheses and commas.
Line through (1,8) perpendicular to
The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them. The constant is given directly by the point we're through:
Let's clear the fractions by multiplying both sides by 20.
Might as well stop here.
Answer: 25 x + 16 y = 153

I cant understand could you make it clearer
Answer:
The answer is (b) ⇒
Step-by-step explanation:
∵ 
∵ √x² = x ⇒ that means to cancel the square root divide
the power by 2
∴ 
∵ √4 = 2 ⇒ √2×2 = √2² = 2
∵ √c³ = 
∴ 
∴ 
∵ In the same base with multiplication we add the power,
in same base with division we subtract the power
∴ 
⇒ 
∴ The answer is (b) ⇒
