Answer:

a) The equation of the straight line passing through the origin and having slope m=-5

 y = -5x

b)  The equation of the straight line in slope-intercept form

 y = 2 x -1

Step-by-step explanation:

Step(i):-

We know that the equation of the straight line passing through the point (x₁, y₁) and having slope  'm'

y - y₁ = m(x-x₁)

a)

Given that the equation of the straight line passing through the origin and having slope m=-5

 y = -5x

Step(ii):-

b)

Given that the equation of the straight line in slope-intercept form

 y = m x +c

 y = 2 x -1
