Question

What is the answer to this equation

Answer 1

`y = - (1)/(3) x`

Answer 2

the equation of the following line (0,0) and (-3,1)

First we find slope of the line using the given points (0,0) and (-3,1)

`slope = (y_2-y_1)/(x_2-x_1)`

(0,0) is (x1,y1) and (-3,1) is (x2,y2)=

`slope = (1-0)/(-3-0)`=
`(-1)/(3)`

Now we use equation y=mx+b

where m is the slope and b is the y intercept

`y=(-1)/(3)x +b`

Plug in (0,0) and solve for b

`0=(-1)/(3)(0)+b`

b=0

So equation of the line is

`y=(-1)/(3)x`
