Question

what is the formula of straight line equatio

Answer 1

Hi Friend !!

y=mx+c
in this m and c are numbers
Hope this helps you buddy !!

Answer 2

The equation of straight line can be find out by different forms depending upon given information.

1=> y=mx+c ....intercept form
m: slope of line
c: y-intercept

2=> (y-y₁ ) = m (x -x₁) ....point slope form
one point (x₁,y₁) m: slope

3=> (y-y₁)=(y₂ -y₁) /(x₂ -x₁)[x-x₁] ...two point form
two points (x₁,y₁)(x₂,y₂)

4=> x/a + y/b = 1 ....intercept form
a: x-intercept b: y-intercept

5=> x cosα + y sinα = p
p: length of normal from origin
α: angle normal makes with x-axis
