Q. Put the following equation of a line into slope-intercept form, simplifying all fractions.3x+18y=18Answer:
Isolate y-term: Isolate the y-term on one side of the equation.To do this, we will subtract 3x from both sides of the equation 3x+18y=18.Calculation: 3x+18y−3x=18−3xSimplifying, we get 18y=18−3x
Divide by coefficient: Divide all terms by the coefficient of y to solve for y. The coefficient of y is 18, so we divide each term by 18. Calculation: (18y)/18=(18−3x)/18 Simplifying, we get y=1−(3x/18)
Simplify fraction: Simplify the fraction in the equation.We simplify the fraction 183x by dividing both the numerator and the denominator by their greatest common divisor, which is 3.Calculation: 183x=(33)x/(318)Simplifying, we get 6xNow the equation is y=1−6x
Rewrite in slope-intercept form: Rewrite the equation in slope-intercept form.The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.Our equation is y=1−6x, which can be rewritten as y=−61x+1 to match the slope-intercept form.
