Q. Put the following equation of a line into slope-intercept form, simplifying all fractions.\newlinex+3y=21 x+3 y=-21 \newlineAnswer:
  1. Move xx to right: To convert the equation into slope-intercept form, which is y=mx+by = mx + b, we need to solve for yy. Let's start by moving the xx term to the right side of the equation.\newlinex+3y=21x + 3y = -21\newlineSubtract xx from both sides to isolate the yy term.\newline3y=x213y = -x - 21
  2. Subtract xx: Now, we need to solve for yy by dividing all terms by the coefficient of yy, which is 33.\newline3y3=x3213\frac{3y}{3} = \frac{-x}{3} - \frac{21}{3}\newlineThis simplifies to:\newliney=(13)x7y = \left(-\frac{1}{3}\right)x - 7
