Find the angle between the lines x - 2y + 5 = 0 and x + 3y - 5 = 0.
Answers
Answer:
x−3y−4=0, 4y−z+5=0, and x+3y−11=0, 2y−z+6=0
Answer: the angle between the lines is θ = 45°
Step-by-step explanation:
x - 2y + 5 = 0 …(1)
x + 3y - 5 = 0 …(2)
General equation of linear function y = mx + b
here m = slope of linear equation
Slope of eq.(1) x - 2y + 5 = 0
Rearrange the equation -2y = - (x + 5)
y = - ( - )
y = - ( - )
y = +
So slope =
Slope of eq.(1) x + 3y - 5 = 0
Rearrange the equation 3y = - x + 5
y = - +
y = +
So slope =
the angle between the lines θ =
=
=
=
θ = 1
θ = (1)
θ = 45°
