Question

How do I write the equation for, (-3, -2), slope = 1/3 using slope intercept form?

Answer 1

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

Explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here slope m =
`(1)/(3)` , then

y =
`(1)/(3)` x + c ← is the partial equation

to find c substitute (- 3, - 2 ) into the partial equation

- 2 =
`(1)/(3)` (- 3) + c = - 1 + c ( add 1 to both sides )

- 1 = c

y =
`(1)/(3)` x - 1 ← equation of line
