9. A. 5x – 3y = 20

B. –3x – 5y = 20

C. –3x + 5y = 4

D. –3x + 5y = 20

-3x+5y=20

Step-by-step explanation:

Standard form is given by ax+by=c

where a , b and c are integers

here we have an equation

so we first multiply the complete equation by 5 to get rid of the fraction

Now subtract 3x from both side to get the required standard form

-3x+5y=20

Step-by-step explanation:

just move y to the side with x and move 4 to the other end

c

step-by-step explanation:

c

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
