A birch tree that is 4 ft tall grows at a rate of 1 ft per year. A larch tree that is 6 ft tall grows at a rate of 0.5 ft per year.
Let the variable t represent time in years and h represent height in feet. In how many years will the trees be the same height?
Which system of equations can be used to solve this problem?
a.{h=4−t
h=6−0.5t
b.{h=5t
h=6.5t
c.{h=1+4t
h=0.5+6t
d.{h=4+t
h=6+0.5t
b?

Nope. The rate of growth is the slope of the line. Study (D) to see why it is the choice.
