they want you to "match up"
d=420-65t with
y=mx+b

if you re-arrange the first equation to this
d = -65 t + 420 and match it to
y = m x + b

you see d matches up with "y"
d-intercept would be translated as y-intercept

b is the y intercept.
what matches with b ?

A car is traveling on a highway. The distance (in miles) from its destination and the time (in hours) is given by the equation  What is the d-intercept of the line? (Remember the slope-intercept form is )

anonymous · Answer

The d-intercept is when t=0 or the b

anonymous · Answer

ok so would that make my answer (0,420) or (420,0)

anonymous · Answer

It is (0,420)
(t,d) or (x,y)

anonymous · Answer

awesome thank you so much for your help!

anonymous · Answer

The x-value always is teh first coordinate and the y value is the second coordinate
so d=-65(0)+420 =420 so our t=0 and our d=420

anonymous · Answer

Even better thank you so much!
