Need help finding the parallel and perpendicular slope

Rudik [331]

Answer:

Step-by-step explanation:

(x₁, y₁) = (19 , -4) & (x₂ ,y₂) = (17, -20)

$Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{-20-[-4]}{17-19}\\\\= \frac{-20+4}{17-19}\\\\= \frac{-16}{-2}\\\\= 8$

m = 8

Parallel lines have same slope.

Parallel slope = 8

Slope of perpendicular line = $\frac{-1}{m}$

Perpendicular slope = $\frac{-1}{8}$

What is the coefficient of b in the expression b+10? Explain

MariettaO [177]

Hello!

A coefficient is a constant multiplied by a variable. As you can see, b is not being multiplied by a number we can see. The thing is, it still has a coefficient. Isn't 1b the same thing as b? This would mean our coefficient would be 1.

I hope this helps!
