Write the standard form of the equation of line through (3, -1) with a slope of -1.
kirill115 [55]

The standard form of a line: Ax+By=C.

The point-slope form: y-y_1=m(x-x_1)

We have the point (3, -1) and the slope m = -1. Substitute:

y-(-1)=-1(x-3)

y+1=-x+3                    <em>add x to both sides</em>

x+y+1=3             <em>subtract 1 from both sides</em>

\boxed{x+y=2}

when u are doing a rotation and it’s a 90 degrees. Do you have to flip the coordinates and change the signs?
Anuta_ua [19.1K]
Hello!

When doing a 90 degree reparation you flip the coordinates and apply to the sign of the quadrant.

For example, If it flips into quadrant one, they will both be positive.

So, in this case it would be Triangle 4.

Hope this helped!

Michael Chan leaves a dock in his motorboat and travels at an average speed of 9 mph toward the Isle of Shoals, a small island o
horsena [70]

Since the motor boat left the dock 2 hours before the tour boat, their meeting point will be 27 miles from the dock from which both boats departed after 3 hours.

<h3>What is the distance?</h3>

Distance is the movement of an object regardless of direction. The distance can be defined as the amount of length an object has covered, regardless of its starting or ending position

We know that r × t = d

r = rate of speed

t = time

d = distance

For the motor boat

9 × t = d = rate × time

For the tour boat

27 × (t - 2) = d = rate × time

When they both cover the same distance in the same amount of time, they will eventually cross paths.

They both cover the same d-mile distance, so:

9 ×t = 27 × (t - 2)

Simplify to get:

9 × t = 27 × t - 54

18 t = 54

t = 3

The motor boat will have traveled at 9 mph for 3 hours to make a distance of 9 × 3 = 27 miles.

The tour boat will have traveled at 27 mph for 1 hour to make a distance of 1 × 27 = 27 miles.

Since the motor boat left the dock 2 hours before the tour boat, their meeting point will be 27 miles from the dock from which both boats departed after 3 hours.
