Is anyone good at geometry? I need help. I don't understand this stuff

HI = 15

Step-by-step explanation:

Since the two triangles are similar, the ratio of their legs are equal.

HI/25 = 3/5

Solving for HI,

HI = (3/5)×25

= 15

i can't see the picture : /

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
