Degree is the value of the highest power of the variable, and hence in this case is 8
Yes it is an algebraic expression mark me brainliest
Bear in mind that for y intercept x=0 and for x intercept y=0
.35x+45=y
x is the miles they run
.35 shows that they charge 35 cents per mile
45 is the constant or the fee they always charge to use their vehicle
