What is the standard form of the line that has x-intercept 6 and y-intercept -2
alisha [4.7K]

Answer:

<h2>x - 3y = 6</h2>

Step-by-step explanation:

The Standard Form of an equation of a line:

Ax+By=C

We have the x-intercept and the y-intercept

x-intercept is for y = 0

y-intercept is for x = 0

Therefore we have two points: (6, 0) and (0, -2).

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

Calculate the slope:

m=\dfrac{-2-0}{0-6}=\dfrac{-2}{-6}=\dfrac{1}{3}

Put it and the value of y-intercept <em>b = -2</em> to the equation of a line:

y=\dfrac{1}{3}x-2

Convert to the standard form:

y=\dfrac{1}{3}x-2            <em>multiply both sides by (-3)</em>

-3y=-x+6            <em>add x to both sides</em>

x-3y=6

I've got a question I think I've got right. Want to be sure tho

<h3>Answer: Choice B is correct</h3>

Explanation:

Theoretically, we expect "6" to show up once every 6 rolls assuming we have a fair die. So about 1/6 = 0.17 = 17% of the time.

The table on the other hand shows "6" showing up 14 times out of 100 to get an experimental probability of 14/100 = 0.14 = 14% which is 3 percentage points less than the theoretical estimate.

Evaluate a Function : f(x) = 7x + 3 When x = 1, 2, 3, 4, 5, and 6
AlladinOne [14]

Answer:

f(1) = 10, f(2) = 17, f(3) = 24, f(4) = 31, f(5)=36, f(6)=45

Step-by-step explanation:

f(1) = 7(1) + 3     f(2) = 7(2) + 3   f(3) = 7(3) + 3    f(4) = 7(4) + 3   f(5) = 7(5) + 3

 f(1) = 7 + 3        f(2) = 14 + 3      f(3) = 21 + 3     f(4) = 28 + 3      f(5) = 35 + 3

   f(1) = 10             f(2) = 17            f(3) = 24            f(4) = 31            f(5) = 38

f(6)= 7(6) + 3

 f(6) = 42 + 3

    f(6) = 45
