22. Write the equation of the line through (3, 4) and (2, 1) in slope-intercept form. (Hint: Find point-slope form first)​
salantis [7]

Answer:

y = 3x - 5

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 )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (3, 4 ) and (x₂, y₂ ) = (2, 1 )

m = \frac{1-4}{2-3} = \frac{-3}{-1} = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 1 ) , then

1 = 6 + c ⇒ c = 1 - 6 = - 5

y = 3x - 5 ← equation of line

Please answer please
Vladimir [108]

Answer:

53.13°

Step-by-step explanation:

Using Sine rule

b / Sin B = a / Sin A

5/ Sin90 = 4 /Sin A

5/1 = 4 /SinA

Sin A = 4/5

A = arc sin(0.8)

A = 53.13010

A = 53.13 °
