Answer:
-18+20=2 so (2,4) is a solution
Step-by-step explanation:
to be able to figure out if the ordered pair is a part of solution, only need to input the x value and see if you can get the output which is y
-9x+5y=2 for (4,2)
-9(4)+5(2) does not equal 2
for :(3,4)
-9(3)+5(4)=2
-27+20 does not equal 2
for (4,3)
-9(4)+5(3)=
-36+15 no solution
for : (2,4)
-9(2)+5(4)=
-18+20=2 so (2,4) is a solution

Answer:
x = - 5, x = 1
Step-by-step explanation:
let f(x) = 0 , that is
(x + 5)(x - 1) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 1 = 0 ⇒ x = 1
Plot the points - 5 and 1 on the number line
