Answer:
Step-by-step explanation:
<u>The slope of the line that passes through points (0, 0) and (-7, -3) is:</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = (-3 - 0)/(-7 - 0) = 3/7
<u>Perpendicular lines have opposite-reciprocal slopes:</u>
Correct choice is C
Answer:
using pythagoras theorem
a^2+b^2=c^2
8^2+x^2=(x+2)^2
64+x^2=x^2+2*x*2+2^2
64+x^2=x^2+4x+4(here x^2 of left hand side and x^2 of right hand side gets cancel)
64=4x+4
64-4=4x
60/4=x
15=x
