Answer 1

• y = x + 10
• y = -x + 6

Explanation:

Equation of Red Line

• Slope (m) = rise/run
• Slope (m) = 1/1 = 1
• y-intercept (c) = (0, 10)
• ⇒ y = mx + c
• ⇒ y = x + 10

Equation of Blue Line

• Slope (m) = rise/run
• Slope (m) = -1/1 = -1
• y-intercept (c) = (0, 6)
• ⇒ y = mx + c
• ⇒ y = -x + 6
