How Do You Solve a Linear Algebra Slope Problem?

In summary, the conversation is about a homework assignment where the question is to find the distance between a point and a line, given the equation of the line and the coordinates of the point. The steps to solve the question are to find the slope of the given line, then use that slope to find the equation of a perpendicular line through the given point. Finally, solving the two equations simultaneously will give the point of intersection, and the distance between that point and the given point can be calculated.

Hey i have a homework assignment due and have no idea how to answer 1 of the questions

the question is

Find m and recal m perpendicular = -1/m. Also sketch the situation showing what the required distance is.

6y+3x=3 ; (8,-1)

all assistance is much appreciated

thanks

I think you need to find the distance between the point and the line. The distance is a line coming out of the point and is perpendicular to the first line.

1) To find the slope, m, of 6y+ 3x= 8, solve for y: the equation will be in the form y= mx+ b.

2) Of course, any line perpendicular to that line will have slope
-1/m. What is the equation of a line through (8,-1) with slope
-1/m? (Use the value of m you found in 1).)

3) Where do those two lines cross? Solve the two equations simultaneously.

4. What is the distance from (8, -1) to the point you found in 3)?
