Trey needs to find the zero of the equation 9x + 2y = 18. Which describes the steps he should take? a. Substitute O for x and solve for y

b. Substitute O for y and solve for x

c. Set 9x + 2y = 0 and solve for x

d. Solve the equation for y and find the coefficient in front of x

a. Substitute 0 for x and solve for y

b. Substitute 0 for y and solve for x

Step-by-step explanation:

Getting the zeros of the given equation is similar to finding the x-intercept and y-intercept of the equation

The x intercept occurs where y = 0

Substituting y = 0 into the expression and getting x we have;

9x + 2y = 18

9x +2(0)= 18

9x = 18

x = 18/9

x=2

Hence the x intercept is 2

Similarly, to get the y intercept, we will substitute x = 0 and get the value of x a shown:

When x =0.

9(0)+2y = 18

0+2y = 18

2y= 18

y = 18/2

y = 9

Hence the zeros of the equations occurs at (2, 9)

The correct options are

-Substitute 0 for x and solve for y

-Substitute 0 for y and solve for x

the answer will be
