A ratio that is equivalent is 18:48
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==

=(x+2)(x+1)
cause
(x+2)(x+1) = x^2 + 2x + x + 2
= x^2 + 3x + 2
answer
(x+2)(x+1)
Answer:
The standard form of the equation of y = -1/4x - 2 is x + 4y = -8 which is C
