40 points please help

ratelena [41]

Answer:

$\huge\boxed{-2}$

Step-by-step explanation:

Use any two points from the line.

(x1,y1) = (0,-2)

(x2,y2) = (-1,0)

Now,

$\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-(-2)}{-1-0} \\\\Slope = \frac{2}{-1} \\\\Slope = -2\\\\\rule[225]{225}{2}$

Hope this helped!

What are the three angle measures in the triangle shown below

Zanzabum

Answer:

B. 31°, 106°, and 43°.

Step-by-step explanation:

the sum of the measures of the angles in a triangle add up to 180°, so:

3x+1+11x-4+5x-7=180

19x-10=180

19x=190

x=10

now that we know x is equal to 10, we can find the three angle measures:

3x+1 -> 3(10)+1 = 31°

11x-4 -> 11(10)-4 = 110-4 = 106°

5x-7 -> 5(10)-7 = 50-7 = 43°

so, the answer is B.
