Which of these linear equation if graphed would be parallel to the line shown ?

Answer explanation

The slope of the line graphed is -2 and it has to be parallel to the line with slope of -2 which is y=-2x+1 !!

What is the equation in slope intercept form of the line that passes through (5, -1) and is parallel to y = -3/5x - 4.

• y = 3/5x - 4

• y = -3/5x + 1

• y = 5/3x - 28/3

• y = -3/5x + 2

Give an equation of a line that is parallel to the line y = -3x

• y = 2/3x - 2

• y = 3x + 2

• y = -3x - 1

• y = -2/3x + 3
