write an equation in slope-intercept form for the line that passes through (-2,5) and is perpendicular to the line described by
Rama09 [41]

Answer:

<h2>         y = ¹/₂x + 6</h2>

Step-by-step explanation:

The product of slopes of perpendicular lines is -1

y = - 2x + 6  ⇒   m₁ = - 2

m₁m₂ = -1

-2m₂ = -1

m₂ = ⁻¹/₋₂ = ¹/₂

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is:  y - y₁ = m(x - x₁)

m = ¹/₂

(-2, 5)  ⇒  x₁ = -2,  y₁ = 5

So the equation in point-slope form:

                                                  y - 5 = ¹/₂(x - (-2))

Therefore:

y - 5 = ¹/₂x + 1

y = ¹/₂x + 1 + 5

<h3>y = ¹/₂x + 6</h3>

Please Help!!!! Solve For L
Sonja [21]
<h3>Given :</h3>

  • \tt B = L - L a f

<h3>To Find :</h3>

  • L = ?

<h3>Solution :</h3>

\tt B = L - L a f

By taking L common from \tt (L - L a f), we get :

\tt : \implies B = L(1 - a f)

\tt : \implies \dfrac{B}{(1 - a f)} = L

\tt : \implies L = \dfrac{B}{1 - a f}

Hence, value of \tt L = \dfrac{B}{1 - a f}
