Answer:

<h2>The slope m = 3</h2>

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 5) and (-1, -4). Substitute:

$m=\dfrac{-4-5}{-1-2}=\dfrac{-9}{-3}=3$

Find x with reasoning

MatroZZZ [7]

Answer:

Angle Sum Property of triangle states that the sum of all the angles of a triangle is equal to 180°

Therefore ,

$\bold{x + (x + 10) + (x - 40) = 180} \\ \\\bold{ x + x + 10 + x - 40 = 180 } \\ \\ \bold{3x - 30 = 180} \\ \\ \bold{ 3x = 180 + 30} \\ \\ \bold{3x = 210 }\\ \\ \bold{x = \cancel{\frac{210}{3}}} \\ \\\bold\blue{ x = 70 \: degrees}$

hope helpful~
