What is the equation of the line that passes through the point (-6, -6) and has a<br> slope of - 1/3
pickupchik [31]

Answer:

The equation of the line is y = -\frac{1}{3}x - 8

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Slope of - 1/3

This means that m = -\frac{1}{3}

So

y = -\frac{1}{3}x + b

Through the point (-6, -6)

This means that when x = -6, y = -6. So

y = -\frac{1}{3}x + b

-6 = -\frac{1}{3}(-6) + b

b + 2 = -6

b = -8

The equation of the line is y = -\frac{1}{3}x - 8

Ivan and Kate live 40 miles apart. Ivan leaves his house at 8:00 a.m.
Triss [41]

Answer: Time at which the meet = 10:17:24 am

Step-by-step explanation: Speed of Ivan = 12 mph

Speed of Kate = 16 mph

Total distance traveled = Initial separation = 40 miles

Ivan leaves his house at 8:00  a.m and Kate leaves her house at 9:30  a.m

If t is the time of catch up after Ivan starting, time taken by Kate is t - 1.5,

We have

            Distance = Speed x Time

         Total distance traveled = Distance traveled by Kate + Distance traveled by Ivan

       40 = t x 12 + (t-1.5) x 16

        40 = 28t - 24

         28t = 64

             t = 2.29 hours

So after 2.29 hours of Ivan's starting they meet,

Time = 8:00 am + 2.29 hours = 10:00 am + 0.29 x 60 minutes = 10:17am + 0.4 x 60 seconds = 10:17:24 am

Time at which the meet = 10:17:24 am

How do I find the y value for point I such that DI and EI form a 3:5 ratio.
liraira [26]
3:5 ratio mean there are 8 "parts" (3 + 5 = 8)

The distance between the x-coordinates is |-3 - 5| = 8.
So each "part" is 8/8 = 1 unit long in the x-direction. 
You want I to be 3(1) = 3 units from D, so the x-coordinate of I is -3 + 3 = 0.

Same deal for y.
|2 - 5| = 3 is the distance between D and E
Each part is 3/8.
3(3/8) = 9/8
2 + 9/8 = 25/8

So the point I is (0, 25/8)
