Solve for x/2 + y/5=1 for y.

Answer : y= -5/2x +5

Step 1. The answer is in slope-intercept form where m is the slope and b is the y-intercept when x=0 at point (0,b). In this example, the answer reveals that m=-5/2 and b=5.

Step 2. To get this equation from x%2F2%2By%2F5=1, use the following steps:

Multiply by 10 to both sides of the equation to get rid of the denominators.

10%2Ax%2F2%2B10%2Ay%2F5=10%2A1

5x%2B2y=10

Subtract 5x from both sides of the equation

5x%2B2y-5x=10-5x

2y=-5x%2B10

Divide 2 to both sides of the equation

2y%2F2=-5x%2F2%2B10%2F2

y=-5x%2F2%2B5 ANSWER

Now here's a plot and note the slope m=-5/2 and y-intercept b=5 at point (0,5)

I hope the above steps were helpful.
