Question

F(r)=-5/9r+4
What is the y intercept

Answer 1

4

Explanation:

The equation of a line in slope- intercept form is

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

f(r) = -
`(5)/(9)` r + 4 ← is in slope- intercept form

with slope m = -
`(5)/(9)` and y- intercept c = 4 → (0, 4 )
