Answer: D
Explanation: I had this answer on my quiz
Answer:
y = 8
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Line] x = -3
Point (1, 8)
<u>Step 2: Find Perpendicular Line</u>
<em>A vertical line's slope is undefined. </em>
The negative reciprocal of an undefined slope is 0.
- Define perpendicular slope: <em>m</em> = 0
- Substitute in <em>m</em> [Slope-Intercept Form]: y = 0x + b
- Simplify: y = b
Given point (1, 8), our <em>y</em>-value is equal to 8.
∴ the perpendicular line is y = 8.
Answer:
B. y - 1 = -4[x - (-3)]
Step-by-step explanation:
Given:
Slope = -4
Point = (-3, 1)
Required:
Point-slope form of the line
Solution:
Equation of a line in Point-slope form is given as y - b = m(x - a).
Where,
a = -3
b = 1
m = -4
Plug in the values
y - 1 = -4[x - (-3)]
