HELP ME PLEASE ITS DUE RN! Consider the line and triangles in the diagram, which of the following statements explains the relati
onship between the slope of the line and features of the triangles? (brainliest) (help!)
1 answer:
Answer:
B) The triangles are similar and have the same ratios for the height to the base . The slope of the line is
.
Step-by-step explanation:
The triangles share the ratio , and the slope of
. This narrows down the options to either A or B. But, the difference between the options are the words "similar and congruent." Congruent means that the triangles are exactly the same shape and size. Similar means that they share a shape but are different sizes. The triangles are similar.
Hope it helps!

I'm not 100% sure how to do this, but it would help if you had any notes/online notes/textbook that shows how to do it (also to see if what I did is the same as the notes)
4. B<u>reak-even point</u> (It's basically the intersection point. Or the point when the two lines meet/the point that is the same for both equations)
I plugged in numbers for x into both equations, until C and R were the same number.
I had x = 1, so I plugged in 1 for x into both equations:
C = 15x + 150 C = 15(1) + 150 = 15 + 150 = 165
R = 45x R = 45(1) = 45
Then I had x = 2, then x = 3, and so on until C and R were the same number (meaning they had the same point), which was (5, 225)
Idk how you are suppose to check the solution because there are multiple ways to do this. I doubt this, but one option is plugging (5, 225) back into the equations:
C = 15x + 150 R = 45x
225 = 15(5) + 150 225 = 45(5)
225 = 75 + 150 225 = 225
225 = 225
5. (I made another sort of table? because I didn't know what kind you were suppose to use) Do the same as #4, and plug in numbers for x until C and R were the same number
6. Do the same as #4 (If you have any questions or information I should know then let me know)
7. y = mx + b
"m" is the slope, "b" is the y-intercept [the y value when x = 0 (0, y)]
The y-intercepts are -2 and 13, so the graph is B. Now you need to estimate the solution(point of intersection) by looking at the graph. It looks around (6,7).
Now you need to check the solution by plugging the point into both equations.
y = 1.5x - 2
7 = 1.5(6) - 2
7 = 9 - 2
7 = 7
y = -x + 13
7 = -6 + 13
7 = 7 The point is the solution
8. The graph is A. Do the same as #7 and estimate a point. I will say around (2.5,6.5) And check this by plugging the point into both equations
y = x + 4
6.5 = 2.5 + 4
6.5 = 6.5
y = 3x - 1
6.5 = 3(2.5) - 1
6.5 = 7.5 - 1
6.5 = 6.5 The point is the solution
9. Graph C, do the same as #7 and #8
10. y = mx + b
"b" is (0,b) or (0,y)
"m" is the slope
(
Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right)
You need to graph the lines of each equation, and find the point of intersection.
11-15. Do the same as #10
If "y" is not by itself, get it by itself.
#13:
x + y = 27 Subtract x on both sides to get "y" by itself
y = 27 - x
