Question

Find the coordinates of the point in which the graph of 4x-5y=20 meets x axis and y axis

Answer 1

Answer:let y = 0 to get x intercept:

4x - 5(0) = 20

4x = 20x = 5

(5, 0)

let x = 0 to get y intercept:

4(0) - 5y = 20

-5y = 20

y = - 4

(0, - 4)

Answer 2

(5, 0 ) and (0, - 4 )

Explanation:

The graph crosses the x- axis when y = 0. Substitute y = 0 into the equation and solve for x

4x - 5(0) = 20

4x = 20 ( divide both sides by 4 )

x = 5

crosses the x- axis at (5, 0 )

The graph crosses the y- axis when x = 0 . Substitute x = 0 into the equation and solve for y

4(0) - 5y = 20

- 5y = 0 ( divide both sides by - 5 )

y = - 4

crosses the y- axis at (0, - 4 )
