Question

Write an equation for the line in the slope-intercept form.

slope= 8/9, y-intercept=-4
A) f(x) = 9/8x +9/2
B) f(x) = -8/9x - 4
C) f(x) = 8/9x - 4
D) f(x) = -8/9x + 4

Answer 1

C

Explanation:

the equation of a line in slope- intercept form is

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

here m =
`(8)/(9)` and c = - 4 , then

f(x) =
`(8)/(9)` x - 4 ← equation of line
