Describe how to draw a line that passes through the origin and has a slope of 3/5
ANEK [815]
The "origin" of a line is simply the points (0, 0)

To draw a line that passes through the origin (0, 0) & has a slope of 3/5, we simply start by drawing a point at (0, 0).

Then, from there, you use the slope to find your next points.

Slope = rise/run

So, 3 is the rise, and 5 is the run.

So, starting from (0, 0), you go up 3 times, and go to the right 5 times. So, (3, 5) is your next point. Just continue doing that and you'll get a line.

marshall27 [118]
I can only write a inequality here but here goes...
since she can atleast type 50 per minute that means the equation would be x >50 (you would also put the line under the > because it can equal it) (x is the amount she can type)

If A = (4,-5) and B = (7.-9), what is the length of AB?​
Nookie1986 [14]

Answer:

5

Step-by-step explanation:

We can figure out the length of AB by using the distance formula.

D = \sqrt{(7-4)^{2} + (-9-(-5))^{2} }\\ D = \sqrt{(3)^{2} + (-4)^{2} }\\D = \sqrt{9 + 16}\\D = \sqrt{25}\\D=5

So the distance is 5
