Parallel Lines Equation

Which of these linear equation is parallel to the linear graph that has the equation y = x + 2 ?

Answer explanation

The slope for y = x + 2 is 1 , and y = x - 3 , the slope is 1 as well , so these lines are parallel because they have the same slope!

Which of these shows a graph of two parallel lines ?

• 
• 
• 
• 

Answer explanation

Parallel Lines NEVER intersect !!

A line g has a y-intercept (0,6) and a slope of -2, is parallel to another line f that crosses the y-axis at (0,2) , where would this line crosses the x-axis ?

• (1,0)

• (-1,0)

• (2,0)

• (-2,0)

A line f has a slope of 3 and a y-intercept (0,4) . which of these equations is parallel to line f ?

Answer explanation

Parallel means same slope m = 3 , and y=3x - 1 has a slope of 3 !!

Line m passes through points (-1,4) and (1,10) is parallel to line n that passes through point (0,1) . What is the equation of line n ?

Use the equations given to determine if the following lines are parallel, perpendicular, neither or both.
y-2=.5(x+3)
y-4=.5(x-2)

• parallel

• perpendicular

• neither parallel nor perpendicular

• both parallel and perpendicular
