The point slope form of the equation of the line that passes Through (-4,3) and (12,1) is y-1=1\4(x-12) what is the standard for

m of the equation for this line

Something is wrong here, the slope is off...

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

m=(1-3)/(12--4)

m=-2/16

m=-1/8

So the point slope form should be:

y-1=(-1/8)(x-12)

The standard form of the line is ax+by=c so we need to rearrange it to reflect the this form...multiply both sides by -8 to get:

8-8y=x-12  subtract 8 from both sides

-8y=x-20  subtract x from both sides

-x-8y=-20  by convention, the coefficient of x should be positive, multiply both sides by -1

x+8y=20

....

Just to show that the equation given you is incorrect..

y-1=(x-12)/4  using the point (-4,3)

3-1=(-4-12)/4

2=-16/4

2=-4  which is obviously incorrect...(they had the wrong slope for the two points given)

HELPPP PLSSSS!! SHOW YOUR WORK!!<br><br>THANKS

I belive it would be B. because of the fact that they are parallel which means their slope should stay the same...but their y-intersept would change

Need help here plss
Ierofanga [76]

Two linear equations can have no solutions, exactly one solution or infinitely many solutions. There will be no solution if the lines are parallel on a graph. There will be exactly one solution if the lines intersect each other on a single point. And finally, there will be infinite solutions if the lines overlap each other perfectly.

A single line however has infinite ordered pair solutions as the line travels infinitely in both directions on the coordinate plane. For example, using the equation y=3x, for any real value of x, we will get a real value for y.

Linear inequalities with two variables have infinitely many solutions. We can use the inequality y>3x as an example. For any real value of x, we will get a real value for y.

I hope this helps!

If 7=42,6=30,5=20 then 3=? find it's value​
AleksandrR [38]

Answer:

6

Step-by-step explanation:

7=42 is 7*6

6=30 is 6*5

5=20 is 5*4; it's multiplied by the number below it, so 3 will be 3*2

The sum of a number w and 3 is less than or equal to ten.
Zinaida [17]
<h2>Answer:</h2>

In this problem we must translate English words into Algebraic Expressions. So we have the following English words:

<em>The sum of a number w and 3 is less than or equal to ten</em>

<em />

So let's do that using two steps:

<h3>1. The sum of a number w and 3:</h3>

Here we have two numbers w and 3. So we must makes the sum these numbers, therefore:

w+3

<h3>2. The sum of a number w and 3 is less than or equal to ten:</h3>

The symbol for the English words less than or equal to is ≤ hence we can write these words as:

\boxed{w+3\leq 10}

As you can see, the algebraic expression is an inequality.
