Which of the following is the equation of a line parallel to the line y = 4x + 1,
Lisa [10]

Answer:

y = 4x - 19

Step-by-step explanation:

The line is parallel to the line whose equation is;

y = 4x + 1

Parallel lines have the same slope so the slope of our line is 4.

The line passes through point (5,1)

Slope = change in y ÷ change in x

Taking another point (x,y) on the line,

Slope = \frac{y-1}{x-5} = 4

y - 1 = 4x - 20

y = 4x - 19

What are the domain restrictions of q^2−7q−8 divided by q^2+3q−4 ?
Maksim231197 [3]
Factorize the polynomials individually; 

q²-7q-8= (q-8)(q+1) <-- denominator 
q²+3q-4= (q-1)(q+4) 

When a number is divided by 0, it becomes indefinite (creating a hole in the graph). 

(q-8)(q+1)=0 
q=8
q=-1

Therefore, the second option.

Hope I helped :)
