Write as a Vector Equality m=-1/5 , b=1
Problem
Solution
Identify the slope-intercept form of a linear equation, which is
y=m*x+b Substitute the given values
m=−1/5 andb=1 into the equation to gety=−1/5*x+1 Express the line in vector form
r=(r_0)+t*v where(r_0) is a position vector to a point on the line andv is the direction vector.Determine a point on the line by setting
x=0 which givesy=1 resulting in the position vector(r_0)=<0,1> Determine the direction vector
v using the slopem=Δ(y)/Δ(x)=(−1)/5 which corresponds to the vector<5,−1> Combine these components into the vector equality
<x,y>=<0,1>+t<5,−1>
