Please answer this question Will giv brainliest !!

B. m=5/4

Step-by-step explanation:

Perpendicular slopes are negative reciprocals. This means they have opposite signs, and their numerators and denominators are switched.

1. Negate the sign

The slope we are given is

m= -4/5

To negate it, switch the sign. It is currently negative. Therefore, switch it to a positive sign.

m= +4/5

Positive 4/5 is also equal to just 4/5, so we can leave it as

m=4/5

2. Find the reciprocal

Currently, the slope we have is

m=4/5

We need to find the reciprocal. To do this, switch the numerator (top number) and denominator (bottom number)

m=4/5 ---flip--> m=5/4

Our final slope is: m=5/4

Therefore, the answer is B. m=5/4

x=30
