Question

Smitty's car breaks down on a country road. He starts walking toward home at a rate of 1.25 miles an hour. After 0.75 hours, he is 3 miles from home. What is the point-slope formula for this information.

Answer 1

so we are finding the distance he is from home

point slope form is
y-y1=m(x-x1)
given the point (x1,y1) and the slope m

so we are given (0.75,3) and the slope is 1.25
wait, the slope is -1.25 since the distance from his home is decreasing
so

y-3=-1.25(x-0.75) is point slope form
