For example, l is the length of short ladder we want to find

Make a comparison
ladder/wall height = ladder/wall height
l/20 = 60/50
l/20 = 6/5
l = 6/5 × 20
l = 120/5
l = 24

The short ladder is 24 ft

Answer:

<h2>The flat pay $25 represents the intercept</h2>

Step-by-step explanation:

To answer this question we need to first understand and compare it with the equation of straight line.

i.e y= mx+c  which is the equation of line

where m= slope

           y= dependent variable

           x= independent variable

          c= intercept

Given

y= 25+5h

comparing both expression we can see that

25 corresponds to c which is the intercept
