How would you solve this(what is the equation of the line that passes through the point (3,4) and has a slope of -2/3?)//delta m

andre [41]

Answer:

$y = -\frac{2}{3}x + 6$

Step-by-step explanation:

y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.

4 = $-\frac{2}{3}$ (3) + b

-2/3 times 3 is -2 so you can fill that in place.

4 = -2 + b

6 = b

So the y-intercept is 6 now we can complete the equation.

$y = -\frac{2}{3}x + 6$

Hope that helps and have a great day!

A fisherman rows his boat toward a town 17 miles upstream. Each day he rows the boat 6 miles upstream, and each night the boat d

Phoenix [80]

The fisherman reaches the town on 4th day.

<u>SOLUTION: </u>

Given, A fisherman rows his boat toward a town 17 miles upstream.

Each day he rows the boat 6 miles upstream, and each night the boat drifts back 2 miles.

We have to find If this pattern continues on which day will he reach the town?

Now, after 1st day distance between him and town = 17 – 6 = 11 miles

And after that night, distance = 11 + 2 = 13 miles

Now, again after 2nd day, distance = 13 – 6 = 7 miles

And after that night, distance = 7 + 2 = 9 miles

Now, again after 3rd day, distance = 9 – 6 = 3 miles

And after the night, distance = 3 + 2 = 5 miles

Now, again after 4th day, distance = 5 – 6 miles = - 1 miles

Here, - 1 miles means that he already reached the town.

Hence, the fisherman reaches the town on 4th day
