The equation in slope-intercept form for the line with slope of 8 and passing through (1,8) is y = 8x

<h3>What is slope intercept form ?</h3>

One of the most widely used forms for expressing a line's equation is the slope intercept form of a straight line. If you know the slope of the straight line and the y-intercept, you can use the slope intercept formula to determine the equation of the line ( the y-coordinate of the point where the line intersects the y-axis). Every point along a line must satisfy its equation in order for it to exist.

y=mx + b is the equation in slope intercept form

x=1, y=8

y=8x+ b

8 = 8 + b

b= 0

The equation in slope-intercept form for the line with slope of 8 and passing through (1,8) is y = 8x

An unprepared student makes random guesses for the ten true-false questions on a quiz. Find the probability that there is at le

hoa [83]

Answer:

0.999

Step-by-step explanation:

At least 1 correct means, 1 correct, 2 correct, 3 correct ... until 10 correct. That would be a long process to calculate.

<em>Instead we use the complement rule to calculate.</em>

<em />

<em />

In true false question, probablity of correct is 1/2 and incorrect is 1/2, hence,

Probability of 10 incorrect is (1/2)^10

Thus,

$P(x\geq1)=1-(\frac{1}{2})^{10}=0.999$

So the answer is 0.999 (rounded to nearest thousandth)

The equation of the line that contains the points (-8, 1) and (0, -5) is

posledela

Answer:

y = -3/4x -5 (G)

Step-by-step explanation:

Find the slope by using the slope formula. (It's hard to format here so look it up)

Basically, it is y2 - y1/x2 - x1

-5 - 1/ 0 + 8

-6/8 = -3/4

The slope is -3/4.

Plug in for y = mx + b

y (y coordinate) = -5

x (x coordinate) = 0

slope (m) = -3/4

-5 = -3/4(0) + b

-5 = 0 + b

b = -5

y = -3/4x -5

Here is the other part sorry

PSYCHO15rus [73]

Answer:

1) 32/5

2) 19/8

3) 34/7

4) 25/3

How to do this

You take the denominator (the number on the bottom), multiply it by the whole number (like in 1, 5*6=30) then add the numerator (the top number) (so 30+2) then add on top of the denominator before you changed anything (32/5)
