Answer:

#1)

Angle A = 30 degrees; 180 - 150 = 30

Angle B = 120 degrees; 180 - 60 = 120

#2)

Angle A = 65 degrees; 180 - 115 = 65

Angle B = 25 degrees; 180 - 155 = 25

Write an equation of the line that passes through the point (6, -9) with the given slope m = 3.

adelina 88 [10]

Answer:

y = 3x - 27

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 )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (6, - 9) into the partial equation

- 9 = 18 + c ⇒ c = - 9 - 18 = - 27

y = 3x - 27 ← equation of line

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from table.

Point (-1, -1)

Point (0, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change and slope are identical.

Substitute [SF]: $m=\frac{-5+1}{0+1}$
Add: $m=\frac{-4}{1}$
Divide: $m=-4$
