Find an equation of the line having the given slope containing the given point slope -9 through (1,-8)
Darya [45]

Answer:

y = - 9x + 1

Step-by-step 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 = - 9, hence

y = - 9x + c ← is the partial equation

To find c substitute (1 , - 8) into the partial equation

- 8 = - 9 + c ⇒ c = - 8 + 9 = 1

y = - 9x + 1 ← equation of line
