Which equation represents the line that is perpendicular to y=3/4x+1 and passes through (-5,11) Will give brainliest!!

y = - x +

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x + 1 ← is in slope- intercept form

with slope m =

Given a line with slope m then the slope of a line perpendicular to it is

= - = - = - , thus

y = - x + c ← is the partial equation

To find c substitute (- 5, 11) into the partial equation

11 = + c ⇒ c = 11 - =

y = - x + ← equation of perpendicular line

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
