Write the equation of a line in slope-intercept form parallel to the line y = -2x + 7 and contains (-1, 3).
JulsSmile [24]

Answer:

The answer is

<h2>y = - 2x + 1</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

From the question the original line is

y = - 2x + 7

Comparing with the general equation above

Slope = - 2

Since the lines are parallel their slope are also the same

Slope of parallel line = - 2

The equation of the line using point (-1, 3) and slope - 2 is

y - 3  =  - 2(x + 1) \\ y - 3 =  - 2x - 2 \\ y =  - 2x - 2 + 3

We have the final answer as

y =  - 2x + 1 \\

Hope this helps you

A tower that is 125 feet tall casts a shadow 173 feet long find the angle of elevation of the sun to the nearest degree
Alik [6]

Applying the tangent ratio, the angle of elevation of the sun, to the nearest degree, is: 36°.

<h3>What is the Tangent Ratio?</h3>

In a right triangle, tan ∅ = opposite length / adjacent length is the tangent ratio.

Given the following:

  • Angle of elevation = ∅
  • Opposite length = 125 ft
  • Adjacent length = 172 ft

Apply the tangent ratio:

tan ∅ = 125/172

tan ∅ = 125/172

∅ = tan^(-1)(125/172)

∅ ≈ 36°
