Question

Which is the equation of a line that has a slope of -2/3 and passes through point (-3,-1)

Answer 1

We just need to put x and y coordinates into equatoins

1)

`y = - (2)/(3) x + 1 \\ - 1 = - (2)/(3) * ( - 3) + 1 \\ - 1 \\eq3`

2)

`y = - (2)/(3) x + 3 \\ - 1 = - (2)/(3) * ( - 3) + 3 \\ - 1 \\eq5`

3)

`y = - (2)/(3) x - 1 \\ - 1 = - (2)/(3) * ( - 3) - 1 \\ - 1 \\eq1`

4)

`y = - (2)/(3) x - 3 \\ - 1 = - (2)/(3) * ( - 3) - 3 \\ - 1 = - 1`

Answer:

`y = - (2)/(3) x - 3`
