I would like to ask anyone if they would mind helping me if they could explain in a way that makes sense, how to find the y-intercept with two points... please help me, google tells me how but my head hurts and it makes no sense TwT ty in advance!!

Answers

Answer:

Ok so the two points that are given need to be in the form of y2-y1 over x2-x1, meaning the x value from the second set of points needs to be subtracted from the x value from the first set of points, and it is the same for the y values. Then that gives you the slope. You add the slope to the equation y=mx+b. The slope is m, so you put the slope in the m spot. If the slope were 3, it would look like y=3x+b because it is in the m spot. Then, you can choose any 1 set of points given and plug it into the equation. I am going to use the slope 3 , like the last example, and plug it in with the set of points. Say the point was (5,2), you will plug the x value, which is 10 in the situation, next to the the slope. The slope will then be 3(5). Then you will plug in the y value, which is 2, into the y place. At the end, the equation will look like this: 2=3(5)+b. Then you multiply 3 and 5, which is 15, and subtract 2 and 15 which will give you -13. The answer will then be -13=b. That is the y-intercept.

Step-by-step explanation:

hey! if you have the equation, for example:

y=3x+4

the y-intercept would be 4! this is an easy hack to use if you already have the equation. in an equation, the number on the very end will always be your y-intercept if it is correctly written in slope intercept form.

if you do not have the equation but have the points, the y-intercept would be the point on the line that touches the y-axis first.

for example:

the line crosses through the 3rd line on the y axis. your y-intercept would be 3. it is the point in which your line crosses on the y-axis line that goes up and down the middle of the graph.

comment on my answer if you have any questions! hopefully this helps.

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.

I know the answer. Just want to see if its close to anyone elses.

Answers

Both answer are correct plz mark me brainlyest

Answer:

The answers below are all right :D

Step-by-step explanation:

My answer: Both are correct because to find the equation u need both the pointslope form and slope intercept form.

Short Answer: Both Samuel and Helena are correct.  Both forms result in the same equation.  Slope-intercept uses slope and a point to find the y-intercept.  Point-slope uses slope and a point to solve for y to form the equation.

Sample Response: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.

Y=2/3x-2
That’s what I got if it’s wrong I’m sorry haven’t done this kind of work in 1 maybe 2 years

Answer:

-3

Step-by-step explanation:

The x-intercept is 3, here's why

First, you need to get the slope

y2-y1

--------

x2-x1

You should get 2/3

Next, you need to use y=mx+b

y= 2/3x+b

2= 2/3(6)+b       You get 6 and 2 from the coordinates

Once this is worked out you'll get y=2/3x-2

To get the x intercept you need to set y equal to 0

0=2/3x-2

Add 2 to each side

0-2 = 2/3x

Multiply each side by 3/2 to isolate x

-2 *3/2 = 2/3x * 3/2

-3 =x

The x intercept is -3

Hope this helped, Brainliest appreciated :)

Ms. Garland bought x number of shirts for the new members of her chorus. The cost for X number of shirts, including $3.99 shipping was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Which equation could be used to find X?
A. 3.99(x + 12.25) = 77.49

B. 3.99x + 12.25 = 77.49

C. 12.25 (x + 3.99) = 77.49


D. 12.25x + 3.99 = 77.49

Answers

77.49 - 3.99 = 12.25 * x

73.5 = 12.25x
