The line having an x intercept of 3 and y intercept of 10<br> Write this in Standard form Ax+By=C

Svetlanka [38]

Answer:

The standard form of the line is 10x + 3y = 10

Step-by-step explanation:

First we need to find the slope of the equation, which we can do using the slope equation and the two points given: (3, 0) and (0, 10)

m(slope) = (y2 - y1)/(x2 - x1)

m = (10 - 0)/(0 -3)

m = 10/-3

Now we can write the equation in slope intercept form since we have the slope and the intercept.

y = mx + b

y = -10/3x + 10

Now we can manipulate the equation to get the standard form.

y = -10/3x + 10

10/3x + y = 10

10x + 3y = 30

Write the standard form of a line that passes through the given points (4,7) and (0,7)

VARVARA [1.3K]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

We have the points (4, 7) and (0, 7) → b = 7.

Calculate the slope:

$m=\dfrac{7-7}{0-4}=\dfrac{0}{-4}=0$

Therefore we have $y=0x+7=7$

The standard form: $Ax+By=C$

<h3>Answer: y = 7.</h3><h3><em>It's a horizontal line.</em></h3>

Johnnas reading rate is 150 words per minute she is reading a 364 page book that has about 275 words on each page at this rate w

ch4aika [34]

Answer:

11 hrs 1 min (i think so based on math)

Step-by-step explanation:

If Johnna's reading rate is 150 words per min and there are 364 pages with about 275 words, you need to multiply 364 and 275 to get 100100 and divide that by 150 to get 667.3333333 round to the nearest tenth which will give you 667.3 and divide that by 60 because there are 60 minutes in an hour to get 11.12222222 and round that to the nearest tenth to get 11.1 which means it will take Johnna 11 hours and 1 minute to read the book. I hope this is correct I'm really sorry if it isn't. :P
