Question

Which of the following lines has a slope of -1/3 and a y-intercept of 6?

x + 3y = 18
3y - x = 18
x - 3y = 6

Answer 1

It would be x + 3y = 18

Answer 2

can you explain it to me please?

Answer 3

Well to know the slop of the equation you would want it to be positive because it's flipped when you find the slope which is -1/3 and as for the y-intercept you would want to make it have it equal by 18 so when you divide by 3, you will get the 6 as your y-intercept. (Makes sense.)
