Answer:
9
Step-by-step explanation:
6x + 2y = 30
9x - 4y = 3
if we double the first equation and add up to second one, we cancel 4y:
- 12x+9x=60+3 ⇒ 21x=63 ⇒ x=3
now we can find y:
- 6*3+2y=30 ⇒ 2y= 30- 18 ⇒ 2y= 12 ⇒ y=6
finally, x+y
The answer is A. (3,0)

Hey there! :)
y = 3/4x - 2
To find the slope and y-intercept, simply use slope-intercept form to understand this.
Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.
Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?
Using this logic, we can come to the conclusion that :
Slope = 3/4 & Y-intercept = -2
