Answer:

I think the answer is a  

Step-by-step explanation:  

A does show the triangle length because both lines on the side has to equal the same but the bottom line is shorter so is 2 cm, 8 cm,. 8 cm.   Hope This Helps!

Answer:

C

Step-by-step explanation:

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

First, simplify the equation to slope intercept form to find the slope;

2x+3y=4
3y=4-2x
y=(-2x+4)/3

The slopes of parallel lines are the same, therefore, the slope of the second line would also be -2/3

Write out the slope intercept form with the information we know and input the coordinates of the point;

y=mx+c
-4=(-2/3)(1)+c
-4+(2/3)=c
(-12/3)+(2/3)=c
-10/3=c

Therefore, the final equation is y=-2/3x-10/3

Hope I helped :)

HELP PLEASEEEE!! First correct answer gets brainliest ! ​

Answer:

2

Step-by-step explanation:

The slope of a line is rise/run.

First, you must choose any two points on the line.

Rise is how many spaces a line moves upward or downward from one point to another.

The run is how many spaces a line moves left or right from one point to another.

It is given that from point M to point N, the line moves up 4 spaces and runs to the right 2 spaces.

  • 4 = rise
  • 2 = run
  • Slope = 4/2, which can be simplified to 2, because 4 divided by 2 is 2.
