SUMMARY

The Cartesian equation of the line defined by the parametric equations (x,y)=(4,-6) + t(8,2) can be derived by eliminating the parameter t. The slope of the line is 1/4, derived from the direction vector (8,2), which indicates that for every 8 units moved in the x-direction, the line moves 2 units in the y-direction. The normal vector (-2,8) is not necessary for this conversion. The final Cartesian equation is y = (1/4)x - 8, representing the relationship between x and y in a standard linear format.

PREREQUISITES

Find the Cartesian equation of each of the following lines.

(x,y)=(4,-6) + t(8,2)

Not sure how to do it, I know that you need the normal which is (-2,8)

I've tried a lot of times and I don't get it

You just have to eliminate the parameter t or you can just use the information you can immediately derive from this equation (i.e. its slope and a point it goes through) to set-up the cartesian equation.

Shouldn't this be posted in the help section?
