Someone please help me thank you

The equation of the line that passes through the points

(-4,4) and (6,4)

is

y=+4

Step-by-step explanation:

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

m= y2-y1/ x2-x1

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (-4,4), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=-4 and y1=4.

Also, let's call the second point you gave, (6,4), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=6 and y2=4.

Now, just plug the numbers into the formula for m above, like this:

m=0

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

y=0x+b

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

(-4,4). When x of the line is -4, y of the line must be 4.

(6,4). When x of the line is 6, y of the line must be 4.

Because you said the line passes through each one of these two points, right?

Now, look at our line's equation so far: y=0x+b. b is what we want, the 0 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-4,4) and (6,4).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!

You can use either (x,y) point you want..the answer will be the same:

(-4,4). y=mx+b or 4=0 × -4+b, or solving for b: b=4-(0)(-4). b=4.

(6,4). y=mx+b or 4=0 × 6+b, or solving for b: b=4-(0)(6). b=4.

See! In both cases we got the same value for b. And this completes our problem.

m came out to be zero, so there is no "mx" term.

c is the correct answer

step-by-step explanation:

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
