Solved by pluggable solver: Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)


3%2Ax-1%2Ay=7Start with the given equation



-1%2Ay=7-3%2Ax Subtract 3%2Ax from both sides

y=%28-1%29%287-3%2Ax%29 Multiply both sides by -1

y=%28-1%29%287%29%2B%281%29%283%29x%29 Distribute -1

y=-7%2B%283%29x Multiply

y=3%2Ax-7 Rearrange the terms

y=3%2Ax-7 Reduce any fractions

So the equation is now in slope-intercept form (y=mx%2Bb) where m=3 (the slope) and b=-7 (the y-intercept)
