Y=2x-3 -- How do you graph this

Mathematics
1 answer:
Debora [2.8K]3 years ago
8 0

Answer:

y = 2x - 3

To plot a graph

you need at least one coordinate and slope

Or

2 coordinates

y = 2x -3

By Comparing with General Equation of a line that is y = mx + c

Here m represents slope

and c is y intercept

which inturn results in m = 2 , c = -3

c = -3

So Coordinate is (0,-3)

Plot (0,-3)

Take a line having slope 2

Then you can plot it

Find all rational roots for p(x)=0
Olenka [21]

Answer

C. (5/2, -1/3)

Step by step explanation

Here we use the rational root theorem.

The possible roots are

+1, +3, +5, +15, +1/2, +3/2, +5/2, +15/2, +1/3, +5/3, +1/6 and +5/6

We have to use the synthetic division to find the correct root of this function.

Here the roots are 5/2 and -1/3

Others are not roots of this function.

Let's check x = 5/2  with synthetic division.

5/2)   6   -13   13   -39   -15

-               15    5    45    15

           --------------------------

             6     2   18     6     0

Similarly x = -1/3 is also root of this function.

Answer: C. (5/2, -1/3)

Which of the following descriptions represents the transformation shown in the image​
Viktor [21]

Answer:  A. 270° rotation, 3 units left, and 2 units up

<u>Step-by-step explanation:</u>

C = (1, 1)        D = (3, 3)          E = (2, -2)

270° rotation counterclockwise means (x, y) = (y, -x)

new C = (1, -1)        new D = (3, -3)         new E = (-2, -2)

3 units left means subtract 3 from the x-coordinate

newer C =( -2, -1)        newer D = (0, -3)      newer E = (-5, -2)

2 units up means add 2 to the y-coordinate

C' = (-2, 1)       D' = (0, -1)       E' = (-5, 0)

Since the first option worked, there is no need to check the other options.
