Question

What is the answer to

Answer 1

y =
`(2)/(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 m =
`(2)/(3)`, thus

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

To find c substitute (9, - 7) into the partial equation

- 7 = 6 + c ⇒ c = - 7 - 6 = - 13

y =
`(2)/(3)` x - 13 ← in slope- intercept form
