What is the equation of the line between #(-1,12)# and #(31,16)#?
See a solution process below:
Fist, we need to determine the slope of the line. The formula for find the slope of a line is:
Substituting the values from the points in the problem gives:
Now, we can use this point-slope formula to write an equation for the line. The point-slope form of a linear equation is:
Substituting the slope we calculated and the values from the first point in the problem gives:
We can also substitute the slope we calculated and the values from the second point in the problem giving:
