Question

solve graphically the system of equations 4x-5y-20=0​

Answer 1

Given Equation

4x - 5y = 20

Now

4x - 5y = 20

When x = 0

4(0) - 5y = 20

0 - 5y = 20

-5y = 20

y = -20/5

y = -4

we get the point (0,-4)

When y = 0

4x - 5(0) = 20

4x - 0 = 20

4x = 20

x = 20/4

x = 5

We Get the point (5 , 0)

Answer

Point ( 0,-4)

point (5,0)
