Question

What is the slope and y-intercept of the graph of 2x + 3y = 18?

slope = -2; y-intercept = (0, 18)
slope = negative 2 over 3; y-intercept = (0, 6)
slope = negative 3 over 2; y-intercept = (0, 2)
slope = 6; y-intercept = (0, negative 2 over 3)

Answer 1

rewrite the equation in form y=mx+c
m is teh slope and c is the y-intercept
2x+3y=18
3y=-2x+18
y=(-2/3)x + 18/3
y = (-2/3)x + 6
So, slope is -2/3 and y-intercept is 6
