Question

Find three integer or decimal solutions to the following equation, and then graph the solution set. 5x-4y=20

Answer 1

we got three points for the given equation (0, -4) ,(2.5 , -1.875) and (5 , 1.25).

Explanation:

We have given,

An equation: 5x - 4y = 20

To draw solutions of equation in a graph we can rewrite given equation as:

5x - 4y = 20

or 5x - 20 = 4y

or y =
`(1)/(4) (5x - 20)`

Now plug three values for x and get corresponding y value.

x : 0 2.5 5

y: -4 -1.875 1.25

Hence we got three points for the given equation (0, -4) ,(2.5 , -1.875) and (5 , 1.25).
