Which choice could be the equation of a line parallel to the line represented by this equation y=2x-3
A y=-1/2x+4
B y=2x+7
C y=-2x+1
D y=3/2x-5

Respuesta :

b) y=2x+7 
lines with the same slope are parallel lines

Answer:

B y=2x+7

Step-by-step explanation:

A first order function, also called a line, has the following format:

[tex]y = ax + b[/tex]

In which a is the angular coefficient and b is the linear coefficient.

Lines are said to be parallel if they have the same angular coefficient.

In this problem, we have that:

[tex]y = 2x - 3[/tex]

This line has an angular coefficient of 2.

So, a parallel line to this line will have an angular coefficient of 2.

The correct answer is:

B y=2x+7
