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


1%2Ax-2%2Ay=4Start with the given equation



-2%2Ay=4-1%2Ax Subtract 1%2Ax from both sides

y=%28-1%2F2%29%284-1%2Ax%29 Multiply both sides by -1%2F2

y=%28-1%2F2%29%284%29%2B%281%2F2%29%281%29x%29 Distribute -1%2F2

y=-4%2F2%2B%281%2F2%29x Multiply

y=%281%2F2%29%2Ax-4%2F2 Rearrange the terms

y=%281%2F2%29%2Ax-2 Reduce any fractions

So the equation is now in slope-intercept form (y=mx%2Bb) where m=1%2F2 (the slope) and b=-2 (the y-intercept)
