Slope-Intercept Form -> Standard Form

Question

Change the following equations into Standard Form:

y = -2/3x + 4

y = x - 5

y = 1/5x - 1

Thank you!!

Answer 1

y = (-2/3)x + 4

multiplies by 3:

3y = -2x + 12

2x + 3y = 12

================================

y = x - 5

0 = x - y - 5

5 = x - y

========================

y = (1/5)x - 1

5y = x - 5

0 = x - 5y - 5

5 = x - 5y
