Answer:

y = 2x - 1

Step-by-step explanation:

Slope intercept form: y=mx+b

point a: (1, 1)

point b: (2, 3)

1. Find the slope of the equation

Equation for slope(mx): (y2- y1)/ (x2-x1)

(3-1)/(2-1)= 2

slope: 2

2. Pick any of the two point to find the "b" and plug in the coordinates of the point to find the y-intercept of the equation.

point a: y=1, x=1

y=mx+b

1=2(1) + b

b= -1

3. Plug the answers you found above into the slope-intercept form

Overall equation:

y=2x - 1

Is this pls help meeeee

Answer:

Step-by-step explanation:

90° counterclockwise rotation: (x,y) becomes (-y,x). so it would be on the upper left square. R would be the farthest to the left with S on top and T to the right. Also the triangle isn't even the same size in the picture. T should be a unit up.

A plane is flying 3900 m above the ground level. The angle of elevation from the control tower to the plane is

Tcecarenko [31]

The horizontal distance to the control tower is approximately 18506.83m

Data;

distance from the ground = 3900m
angle of elevation = 11.4 degrees
horizontal distance = ?

<h3>Trigonometric Ratio</h3>

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.

$tan\theta = \frac{opposite}{adjacent} \\tan11.4 = \frac{3900}{x}\\x = \frac{3900}{tan11.4}\\ x = 18506.83m$
