If the straight line passing through a(-7, -5) and b(-3, x) is parallel to another straight line of slope 2, find the value of x.

x =  3

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(- 7, - 5) and (x₂, y₂ ) = B(- 3, x), then

m = ← equate to 2, that is

= 2 ( multiply both sides by 4

x + 5 = 8 ( subtract 5 from both sides )

x = 3

its a trick question
