for the graph y= 12 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an
ra1l [238]

y = 12 is a line in which every point has a y-coordinate of 12 no matter what the x-coordinate is. That means that y = 12 is a horizontal line. The equation of line y = 12 can be written as y = 0x + 12 clearly showing m = 0 (slope is zero) and the y-intercept is 12. A line parallel to line y = 12 has the same slope, so its slope is also zero.

A line perpendicular to y = 12 is a vertical line. For a vertical line, the slope is undefined because it involves division by zero which is undefined in math.

What is the slope- intercept form of 4x+5y=20
True [87]

Answer:

y = -4/5x + 4

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Standard Form:   4x + 5y = 20

<u>Step 2: Rewrite</u>

  1. Subtract 4x on both sides:                    5y = 20 - 4x
  2. Divide 5 on both sides:                          y = 4 - 4/5x
  3. Rearrange:                                              y = -4/5x + 4

Answer:

x = 6

Step-by-step explanation:

In similar triangles,  corresponding sides are in same ratio

\frac{x+3}{3}= \frac{6}{2}\\\\ \frac{x+3}{3}=3\\\\x+3 = 3*3\\\\x+3 = 9\\\\x = 9-3\\\\x = 6
