Answer:

y = 2x-17

Step-by-step explanation:

We have a point and a slope, we can write the equation in point slope form and then convert to slope intercept form

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

y-1 = 2(x-9)

Distribute

y-1=2x-18

Add 1 to each side

y-1+1 = 2x-18+1

y = 2x-17

This is slope intercept form

How much was invested in the energy
Fofino [41]

The time it will take before Diego catches up with Linh will be after 8 hours

Let :

  • Distance traveled = d

<u>Diego</u> :

  • Travel speed = 75 mph
  • Travel time = t

<u>Linh</u>:

  • Travel speed = 60 mph
  • Travel time = t + 2

Recall :

  • Distance covered = speed × time

  • Distance covered by Linh = 60(t + 2)
  • Distance covered by Diego = 75t

<u>Time</u><u> when Diego catches up with Linh</u> :

Diego's distance = Linh's distance

75t = 60(t + 2)

Solve for t ;

75t = 60t + 120

Collect like terms

75t - 60t = 120

15t = 120

Divide both sides by 15 to isolate t

t = (120 / 15)

t = 8

Hence, Diego will catch up with Linh after 8 hours.
