(1, 3) and (-3, -5) write a linear equation given the two points

Mathematics
1 answer:
Firlakuza [10]2 years ago
7 0

Answer:

y = 2x + 1

Step-by-step explanation:

1. Find the slope;  (change in y values)/(change in x values)

Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2

2. Find the y-intercept (b) using  the slope intercept formula: y = mx + b

    m = 2 and using point (1, 3) , solve for "b"

       y = mx + b

       3 = 2(1) + b

       3 = 2 + b

      1 = b

3.  Write the linear equation: y = 2x + 1

Find the terminal point on the unit circle determined by 11pi/6 radiants
irga5000 [103]

Answer:

(\frac{\sqrt{3}}{2},-\frac{1}{2})

Step-by-step explanation:

The unit circle has the parametric equation:

x=\cos \theta

y=\sin \theta

where \theta=\frac{11\pi }{6} in our case is the terminal side of the angle in standard position.

We substitute to get:

x=\cos \frac{11\pi }{6}=\frac{\sqrt{3}}{2}

y=\sin \frac{11\pi }{6}=-\frac{1}{2}

\therefore (\frac{\sqrt{3}}{2},-\frac{1}{2}) is the required point.

Which relations are functions?<br><br><br><br> Choose all answers that are correct.
-Dominant- [34]
Hello!

In a function, each input has only one output. In A, three has two outputs, 4 and 5, so A is not a function.

In B, you can use something called the vertical line test to see if each x value has one y value as an output. You move an imaginary vertical line across the graph, and if it intersects with two points it is not a function. If we do this on our graph, it will not intersect two points. Therefore, B is a function.

In C, we can see that each input has one output, or there are all different inputs, so C is a function.

For D we can use that vertical line test again. It intersects both the points (-1,1) and (-1,6) so D is not a function

Our final answers are B and C.


I hope this helps!
