y=7 y=7determine slope

Question

y=7

 

y=7 determine slope/parellal lines/perpendicular line

Answer 1

Determine Slope: First, the equation for a line is y=mx+b, solve for slope (m)

 

Since x is your variable, the equation is written y=0*x+7

 

y=7 is a horizontal line

 

Lastly, m=0

 

Parallel lines have the same slope (m) but different y-intercepts (b), reuse the equation for a line to find a parallel line.

 

Perpendicular lines have the product of the slope to equal -1. Since there is no product algebraically that equals 0*(-m)=-1, the perpendicular slope is undefined since there would be a zero in the denominator (rearranging the equation for a perpendicular slope -m=-1/0==> undefined)

 

Hope that helps.
