# Problems on Linear Equations

1.Graph each line using y-intercept and slope.

y+4x=8

2.in each case determine whether the lines are parallel,perpendicular,or neither.

y=x+7

y=-x+2

3.the line is parallel to -3x+2y=9 and contains the point(-2,1)

4.Find the equation of each line in the form y=mx+b if possible.

the line through(3,2) with undefined slope

5. n varies directly as q, and n=39 when q=3.Find n when q=8

6.find the variation constant, and write a formula that expresses the indicated variation.

c varies inversely as d, and c=5 when d=2

Thanks for using Brainmass.

1.) The graph of the line y + 4x = 8 is: (convert first to y = -4x + 8 to get the slope and y-intercept)

2.) The lines are perpendicular. It ...
