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

Step-by-step 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
