b) , slope is 25

c) 350 miles

Step-by-step explanation:

a) Proportional relationships are linear functions that pass through the origin.

b) Proportional relationships can be written as , where is a constant of proportionality. Substitute any point the line passes through to find this constant.

c) Substituting into our function:

y=mx+b

step-by-step explanation:

m slope

b y-intercept

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
