Answer:

Step-by-step explanation:

The line contins points: (-5, -3) and (5, -5) so the slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-5-(-3)}{5-(-5)}=\dfrac{-5+3}{5+5}=\dfrac{-2}{10}=-\dfrac15$

and y-intercept is b = -4

Elza [17]

Given:

A company wants to select 1 project from a set of 4 possible projects.

Consider the options are:

a. $X_1+X_2+X_3+X_4=1$

b. $X_1+X_2+X_3+X_4\leq 1$

c. $X_1+X_2+X_3+X_4\geq 1$

d. $X_1+X_2+X_3+X_4\geq 0$

To find:

The constraints that ensures only 1 will be selected.

Solution:

It is given that the company wants to select 1 project from a set of 4 possible projects. It means the sum of selected projects must be equal to 1.

$X_1+X_2+X_3+X_4=1$

Therefore, the correct option is (a).
