Y=mx+b is standard form. b = y- intercept m = slope Using the information you’ve provided... m = -2/3 This is because -2/3 is the slope. b = 0 This is because the y-intercept is at the origin. Using the information, fill in the standard form. y=-2/3x +0 or y = -2x I hope this helps!! Feel free to ask any questions!
