Q. Put the following equation of a line into slope-intercept form, simplifying all fractions.x+3y=−21Answer:
Move x to right: To convert the equation into slope-intercept form, which is y=mx+b, we need to solve for y. Let's start by moving the x term to the right side of the equation.x+3y=−21Subtract x from both sides to isolate the y term.3y=−x−21
Subtract x: Now, we need to solve for y by dividing all terms by the coefficient of y, which is 3.33y=3−x−321This simplifies to:y=(−31)x−7
