Question 12(Multiple Choice Worth 1 points)
daser333 [38]

The equation of a line is y=-1/4x-7, (option 1)

<h3>What is the equation of a line? </h3>

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.

<h3>How do you find the equation of a line?</h3>

Write the equation in the form y = mx + b to find the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept.

Given:-

Equation of the line is y=4x+8 

The point through which the line passes (-8,4).

here the slope of the line is m1=4

To find the perpendicular line we know the formula

m1*m2=-1

By putting the value of m1 we get m2= -1/4

By using the one-point formula of the line we have

=>(y-y1)=m2*(x-x1)

By putting the values of y1 and x1 we get

(y1,x1)=(-8,4)

=>(y+8)=-0.25*(x-4)

y+0.25x+7=0

Hence the desired equation of the line is y=-1/4x-7

Answer:

700,000

Step-by-step explanation:

To explain this, we need to know the basics.

If you look at the number 790,390, you should automatically know that you can also write the same number as:

700,000 + 90,000 + 300 + 90

How did we do this?

Because each number in 790,390 has a <u>value.</u>

In fact, we can do this for any number! Like this:

12,345

You can also write the same number like this:

10,000 + 2,000 + 300 + 40 + 5

Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000

Examples:

12,345

The 3 in this number stands for 300, since it is in the hundreds place.

678,900

The 7 in this number stands for 70,000 because it is in the ten thousands place

Now you know!
