Answer:
Answer: y = -x + 7
Step-by-step explanation:
The general slope-intercept equation:
[tex]y = mx + b[/tex]
• It's just a matter of making y the subject:
[tex]4x - 4y = 28[/tex]
• Subtract 4x from either sides [ additional rule of equality ]
[tex](4x - 4y) - 4x = 28 - 4x \\ \\ - 4y = - 4x + 28[/tex]
• Then divide all sides by -4 [ division rule of equality ]
[tex] \frac{ - 4y}{ - 4} = \frac{ - 4x}{ - 4} + \frac{28}{ - 4} \\ \\{ \boxed{ \boxed{ y = - x + 7}}}[/tex]
