What is the rate of change, the initial value, and the equation of the line that goes through the points #(1, 5)# and #(2,7)#?
Rate of Change: 2
Initial Value: 3
The rate of change, or the slope, is calculated as
We'll next find the initial value. The slope-intercept equation of a line is
Point: (1, 5)
Thus, our initial value is
