Write an equation for the line passing through the given pair of points. give the final answer in standard form (-4,-2) and (3,-
Andrew [12]

Answer:

y = -2/7x - 22/7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-4, -2)

Point (3, -4)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-4+2}{3+4}
  2. Add:                              m=\frac{-2}{7}

<u>Step 3: Find y-intercept </u><em><u>b</u></em>

  1. Define:                    y = -2/7x + b
  2. Substitute:              -4 = -2/7(3) + b
  3. Multiply:                  -4 = -6/7 + b
  4. Isolate <em>b</em>:                 -22/7 = b
  5. Rewrite:                   b = -22/7

<u>Step 4: Write linear equation</u>

y = -2/7x - 22/7

Two parallel lines are crossed by a transversal what is the value of A?
gulaghasi [49]

Answer: 63 degrees (second choice)

The two angles shown are corresponding angles. They are both on the bottom side of their adjacent parallel line, and at the same time, they are also on the left side of the transversal line. This is why they are corresponding angles.

Corresponding angles are congruent if you have a set of parallel lines like the diagram shows. So that's why a = 63.

What is the ratio for
sweet [91]

Answer:

12/13

Step-by-step explanation:

By definition, for a right triangle with an internal angle X

sin X = length of opposite side / length of hypotenuse

in this case,

for angle F, the opposite side = GH and the hypotenuse is HF

hence

sin F = GH / HF = 12/13
