Question

Find ordered pair that is solution for liner equation 4x - 5y=20

Answer 1

Answer:

(0,-4) (5,0)

Step-by-step explanation:

4x-5y=20

First, we must put the equation into slope intercept form: y= mx+b

5y=4x-20=y=4/5x-4

The y intercept, by definition, is b. In this scenario, b is -4.

One ordered pair that works is (0,-4).

Also, we can find the ordered pair for the x intercept. By definition, the x intercept is the value of x when y equals zero. hence, we substitute 0 for y and then we can find an ordered pair that works and solve for x!:

1. 0=4/5(x)-4= 4=4/5x
2. 4x=20
3. x=5

Therefore, (5,0) works as well!
