The graph of the equation y = 2.5x is the graph in Choice A where evidently, the slope of the graph is 2.5.
To determine which graph is the graph of the equation y = 2.5x;
We must know that the equation takes the slope-intercept form of the equation of a straight line;
Given by; y = mx +c.By comparison, the slope, m = 2.5 and the intercept, c = 0.By observation, the graph drawn in Choice A has a slope of 2.5.
This is evident when we set the value of x = 2, we consequently get the value of y = 5.
The graph of Choice A is has a point represented by the coordinates, (2,5).
Ultimately, the correct answer is Choice A.

Describe the slope of the line.
Answers
the slope is 4/3.
it’s positive because the line is rising/going up
the slope is 4/3 because it rises 4 units and goes to the left 3 units.
The slope of line from the given graph is 4/3.
The coordinates of line from the given graph are (4, 3) and (1, -1).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Now, put (x1, y1) = (4, 3) and (x2, y2) = (1, -1) is slope formula, we get
Slope = (y2-y1)(x2-x1)
= (-1-3)/(1-4)
= 4/3
Therefore, the slope of line from the given graph is 4/3.

#SPJ2
while holding her cat, Mya steps on a scale, the scale reads 127 pounds. Alone, Mya weighs 112 pounds. Write an addition equation to find the weight of Mya's cat.
Answers
Answer:
127+(-112)=15
Step-by-step explanation:
If you subtract 112 from 127, you can find the difference. Since 112 is Mya's weight, and the total is 127, we need to find out how much weight is left over after we take away Mya's weight, which would be the cat's weight. So if you follow the expression, which is 127+(-112), you would get a sum of 15 pounds. Since this is an addition problem, the expression would be 127+(-112) instead of 127-112. I hope you understand. The difference between 127 and 112 is the cat's weight, so the cat weighs 15 pounds.

What is the mZACB?

O 50°
(4x)
O 90°
O 180°
(7x-20)
C
Answers
Answer:
50 degrees
Step-by-step explanation:
The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°

Answers
Answer:
If the graph of the line passes through the origin, it means that the graph has no y-intercept
Step-by-step explanation:
Here, we want to interpret the y-intercept of a graph that passes through the origin
If the y-intercept of a graph passes through the origin, it means that the value of the y-intercept is zero
In other words, the graph has no intercept on either the y or x axes

to find the slope-intercept formula of these charts: (i'm guessing that that's what your teacher wants? you forgot to include their directions in the images)
you need to use y = mx + b
to find m, you take two coordinates and then do (y2 - y1)/(x2 - x1)
to find b, figure out what y is when x = 0.
you can either do this by looking at the chart and finding 0 on the x side, or if that isn't there, take a different point and insert the y and x values into what you have so far. if you enter the points correctly and have an m, the only letter you should have left is b. so all you'd need to do from there is solve the equation for b!
