What is the slope-intercept form of this equation 3x+9y=18

y = mx + b

m: slope

b: y-intercept

3x + 9y = 18

-3x            -3x

9y = -3x + 18

/9           /9

y = -3/9x + 2   OR  y = -1/3 + 2

m = -3/9 OR -1/3

b = 2

PLEASE RATE AS THE BRAINLIEST ANSWER! THANK YOU! :)

i think it is c, not positive though

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
