-3x+9y =18

add 3x to each side

9y = 3x+18

divide by 9

y = 3/9 x +18/9

y = 1/3 x+2

the slope is 1/3

the y intercept  is 2

-3x+9y =18  

let y=0 to find the x intercept

-3x=18

divide by -3

x=-6

the x intercept is -6

2x + 4y = 12 y = x – 3 What is the solution to the system of equations? (–1, 8) (8, –1) 5 1/2 1/2 5
Goryan [66]

Answer:

The solution is (8, -1).

Step-by-step explanation:

2x + 4y = 12..........(1)

y = 1/4x – 3 ..........(2)

Substitute y = x - 3 in equation (1):

2x + 4(1/4x - 3) = 12

2x + x - 12 = 12

3x = 24

x = 8.

Now substitute for x in equation (2):

y = 1/4 *8 - 3

y = -1.
