Answer:

D

Explanation:

for line on left

calculate the slope of the lines using the slope formula

m =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 1) ← 2 points on the line

m =
(1-0)/(0-(-2)) =
(1)/(0+2) =
(1)/(2)

the line crosses the y- axis at (0, 1 ) ⇒ y- intercept = 1

------------------------------------------------------

for line on right

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 2) ← 2 points on line

m =
(-2-0)/(0-(-2)) =
(-2)/(0+2) =
(-2)/(2) = - 1

the line crosses the y- axis at (0, - 2 ) ⇒ y- intercept = - 2

Then


(1)/(2) p = - 1 ( multiply both sides by 2 )

p = - 2

-----------

1 + q = - 2 ( subtract 1 from both sides )

q = - 3
