Question

What is the y-intercept of the equation 4x + 5y = 20?

(0, 4)
(0, 5)
(4, 0)
(5, 0)

Answer 1

(0,5)

Explanation:

Answer 2

(0, 4 )

Explanation:

the equation of a line in slope- intercept form is

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

given

4x + 5y = 20 ( subtract 4x from both sides )

5y = - 4x + 20 ( divide through by 5 )

y = -
`(4)/(5)` x + 4 ← in slope- intercept form

with y- intercept c = 4 or in coordinate form (0, 4 )
