Write the equation of a line parallel to the given line but passing through the given point y=1/4x-2;(8,-1) |
you want a line parallel to y=1/4x-2 so it needs to have the same slope: m=1/4 the slope-intercept form of a line is y=mx+b y=(1/4)x+b plug in (8,-1) for (x,y) to find b: -1=(1/4)(8)+b -1=2+b b=-3 y=(1/4)x+b y=(1/4)x-3 Answer: y=(1/4)x-3 Check Answer with Calculator: You can check this answer by graphing it: y=(1/4)x-3; (8,-1) |
