Select the equations of the lines that are parallel to the line whose equation is y = 3x + 5.

6x+2y =12
-3x+ y=8
3y=9x
y =1/3-x

Answer:

y=3x+8

y=3x

Explanation:

We have to find an equation that is parallel to y=3x+5.

y=mx+c is equation of line where m is slope and c is y-intercept.

The slope of Parallel lines are equal.

hence, the lines which have slope equal to 3 are parallel to y=3x+8

Choice B is:

-3x+y=8

make above equation in slope-intercept form,we get

y=3x+8 this equation has slope equal to 3.

hence,-3x+ y=+8 is parallel to y=3x+5.

Choice C is :

3y=9x

make above equation in slope-intercept form,we get

y=3xthis equation has slope equal to 3.

hence,3y=9x is parallel to y=3x+5.
