What is the equation of the line that passes through (1, 2) and (8,9) in slope-intercept form?

Neporo4naja [7]

Answer:

The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: $y = x+1$

Step-by-step explanation:

The slope-intercept form of line is given by the formula:

$y = mx+b$

Here m is the slope and b is the y intercept

Given

$(x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)$

First of all, the slope has to be found

$m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1$

Putting m=1 in the equation

$y = x+b$

Putting the point (1,2) in the equation to find the value of b

$2 = 1+b\\b = 2-1\\b = 1$

The equation is:

$y = x+1$

Hence,

The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: $y = x+1$

Write the algebraic expression that matches each graph.

goldfiish [28.3K]

Answer:

f(x) = |x - 2| - 2

Step-by-step explanation:

Based on the shape of the graph, it's an absolute value function.

so the template for it is f(x) = |x|

From there, you can make some additions to show how much the graph has shifted from the template equation

since the graph went over to the left by 2 units and down by 2 units, this is added into the equation as follows:

f(x) = |x - 2| - 2

Robin and Shaon got 5/6 and 4/5 of the total marks. Robin obtained 30 more marks than Shaon.What is the total marks?

Natasha2012 [34]

Answer:

Robin= 750

Sharon= 720

Step-by-step explanation:

let the total marks obtained be X

from question, Robin = 5X/6

Shaon= 4X/5

then, 5X/6= 4X/5+30

or, 5X/6= 4X+150/5

or 25X=24x+900

or,X= 900

therefore robin=750

Shaon = 720

I NEED HELP PLEASE I WILL MARK BRAINLIST<br><br> The question is in the screenshot

Ivan

The answer is unreasonable because the value of x is between 2 and 3.The error is : she did not introducing logs in solving the equation.

Step-by-step explanation:

The question is $7^x=95$

Here answers is unreasonable because, she can test with powers of seven like;

7²=49

7³=343

So this means the value of x lies between 2 and 3, so here answer 11.71 is unreasonable

b) In this case, to solve the equation, introduce logs both sides

$7^x=95$

$log7^x=log95\\\\\\xlog7=log95\\\\\\x=\frac{log95}{log7} \\\\\\x=2.340$
