Answer:
Step-by-step explanation:
Subtract x on both sides
Divide both sides by 3
To find the y-intercept, let x = 0
y = 0, therefore the function crosses the y-axis at the origin.
To find the x-intercept, let y = 0
x = 0, therefore the function crosses the x-axis at the origin too.
The slope of the function is -1/3, from the origin, go down 1 and right 3
slope is 1/3
Explanation:We apply the slope formula:
