Question

Write the equation of the line
perpendicular to y = *x+7 with a
y-intercept of (0-1)

Answer 1

Answer: y = -x - 1

Explanation:

Use the Point-Slope formula:
`y - y_1=m_(\perp)(x-x_1)` where

• (x₁ , y₁) is the given point (0, -1)
• 
  `m_(\perp)\ \text{is the opposite reciprocal slope of the given line}\implies m_(\perp)=-1`

Insert those values into the formula and solve for y:

y - (-1) = -1(x - 0)

y + 1 = -x

y = -x - 1
