A florist charges $25 for a vase plus $4.50 for each flower. The total charge for the vase and flowers is given by the function

gtnhenbr [62]

Part 1
All that’s being affected here is the b value in y=mx+b, so your line will just move up to have a y-intercept at (0,35) the equation will be y=4.5x+35

Part 2
Here the m value is being changed so your line will just flatten out a bit and the new equation will be y=3x+25

Hope this helps!
