linnea is renting a bike. It costs $4.50 per hour plus a $5 deposit. What is the equation of the line in slope intercept form.

Question

y=mx+b

b= y intersection

m=slope

x=x axis (East to West)

y=y axis (North to East)

Answer 1

y & x will just be y & x in your equation, while the two numbers you were given will replace m & b.

Remember that the slope (m) is the RATE OF CHANGE. Which value changes the total cost of renting the bike? Is it the rate per hour or the $5 deposit? (HINT: "per" is usually a good indicator of the slope.)

Similarly, which value will stay the same, regardless of how long she has the bike? This will be your y-intercept, or starting value.

Your final equation should be y=4.50x+5, since the $5 deposit doesn't change but the total cost depends on how long Linnea keeps the bike.
