Q. Put the following equation of a line into slope-intercept form, simplifying all fractions.3x−2y=−14Answer:
Move x term: Isolate the term with y on one side of the equation.To do this, we will move the term with x to the other side by subtracting 3x from both sides of the equation.3x−2y−3x=−14−3xThis simplifies to:−2y=−3x−14
Divide by coefficient: Divide every term by the coefficient of y to solve for y. The coefficient of y is −2, so we divide each term by −2 to isolate y. (−2y)/(−2)=(−3x)/(−2)−14/(−2) This simplifies to: y=(3/2)x+7
Check slope-intercept form: Check that the equation is now 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 y=23x+7 is in this form, with a slope of 23 and a y-intercept of 7.
