Fiona wrote the linear equation y =2/5 x – 5. when henry wrote his equation, they discovered that his equation had all the same solutions as fiona’s. which equation could be henry’s?
x –5/4 y = 25/4
x – 5/2y = 25/4
x –5/4 y =25/2
x –5/2 y = 25/2

yeah its d because of the x+y=c form

Step-by-step explanation:

is should be y = 5x

step-by-step explanation:

correct me if im wrong
