Question

A car is traveling on a highway. The distance (in miles) from its destination and the time (in hours) is given by the equation d=420-65t What is the d-intercept of the line? (Remember the slope-intercept form is y=mx+b

Answer 1

for "d intercept" t =0, then d(t=0)=420

Answer 2

Answer: 420 (miles)

Explanation:

Given: A car is traveling on a highway. The distance (in miles) from its destination and the time (in hours) is given by the equation :

`d=420-65t`

To calculate the d- intercept of the line, substitute t =0 in the given equation , we get

`d=420-65(0)\\\\\Rightarrow\ d=420=65-0\\\\\Rightarrow\ d=420`

Hence, the d-intercept of the line is 420 (miles).
