Question

Find the x and y intercept. -4x+5y=-20

Answer 1

1-st u take x=0 and find y,5y=-20--->y=-4 A(0;-4)
2nd-u take y=0 and find x,-4x=-20--->x=5 B(5;0)

Answer 2

you can find your x intercept by letting y=0 and
you can find your y intercept by letting x=0

-4x+5y=-20 here let y =0 we get
-4x+5(0)=-20
-4x =-20
x= -20/-4
x= 5 answer

-4x+5y=-20 here let x =0 we get
-4(0)+5y=-20
5y=-20
y=-20/5=4 answer

Answer 3
