2. What is the equation of the line parallel to the line whose
equation is 5y + 9 = -2x ?
[1] y=-2x +3 [2] y = 2x + 1
B] y = x+4
[4] y=-x-1

Respuesta :

gmany

Step-by-step explanation:

Paralle lines have the same slope.

The slope-intercept form of an equation of a line:

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

m - slope

b - y-intercept

We have

[tex]5y+9=-2x[/tex]

Convert to the slope-intercept form:

[tex]5y+9=-2x[/tex]           subtract 9 from both sides

[tex]5y=-2x-9[/tex]         divide both sides by 5

[tex]y=-\dfrac{2}{5}x-\dfrac{9}{5}\to m=-\dfrac{2}{5}[/tex]

Each of the answers to choose from is not the line equation sought.

The equation:

[tex]y=-\dfrac{2}{5}x+b[/tex] where b is any real number.
