Question

Which equation describes the line graphed above? A. -4x-5 B. -1/5x-4 C. -5x-4 C. -4x-1/5

Answer 1

Answer: B

Explanation:

The line go down one and turn right 5

So slope = -1/5x

And the y intercept is at -4

So B is the correct answer

Answer 2

Answer:

               B.  -¹/₅x-4

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
