y=-4x+4
A good way is to give numbers for x and see what y is. I've done enough of these to see it in my head.
All you need is two points. The y-intercept is 4 because that's when x is 0. (0,4)
Then go right unit then down 4 and that's your next point.
0=-4(1)+4
Which is (1,0)

Where can you find an online math compass?
So far, there is probably not one online. You'll most likely have to buy one. The reason why there isn't one online is because its a drawing tool for making perfect circles. The closest thing to it could be Paint. You just have to use the shape tool.
What is the solution to x2 plus 2x equals 410 the solution is between 7 and 8?
The answer is (3.5)2 plus (4)2 equals 410.
How do i solve this equation . C-2 - 4 equals 3?
You would do it it by oppisites. 3+2+4=9 which equals C.
the answer is infinte.
reason:when you add the two terms ,the numerator is a quadratic equation but denominator is a linear in x ,,,, so as x tends to infinite the function tends to infinite
What is the integral of 1 divided by the square of the hyperbolic sine of x with respect to x?
∫ 1/sinh2(x) dx = -cotanh + C
C is the constant of integration.
What is the factor of the trinomial 7x square plus 7x-14 in polynomail in descending form?
you set it equal to zero
7x^2 + 7x - 14 = 0
since there is a common factor of 7, you can divide each term by that, including the zero on the other side, which just gives you zero again...
(x^2 + x - 2) = 0
You have to find two numbers that multiply to give you the coefficent of the third term (c = -2), and add to give you the coefficient of middle term (b = 1)
so, +2, and -1 add to give you +1 (b), and multiply to give you -2 (c).
so the factors are:
x+2 and x-1
(and therefor the roots are x= -2, and x =1, but you just asked for the factors)
What is the derivative of 12013.995 x 0.7798x?
If the middle x means multiply then...
y = 12013.995*0.7798x
y = 9368.513301x
y' = (1)9368.513301x1-1
y' = 9368.51330
What is the x-intercept for this linear equation 5 x - 4 y equals 18?
There is one simple way to find the answer to this.
The x-intercept occurs when y = 0 as this is the equation of the x-axis. Along the x-axis, the value of the y is always zero.
There fore you can take the value y = 0, substitute into the equation and then solve for x.
e.g.
5x - 4 x 0 = 18
5x = 18
x = 3.6
Hence the x-intercept is when y = 0 and x = 3.6
This method also translates to how to find the y-intercept. The only difference is that you substitute x = 0 into the equation.
Why is my TI 84 plus silver edition not letting me change the x and y list values for LinReg(ax b)?
Additional Information:
When I enter the LinReg it turns up, on the screen,
"LinReg
y=ax+b
a=[some value]
b=[some value]
r^2=[some value]
r=[some value]"
From looking at other people's calculators I'm pretty sure that there's supposed to be another screen it takes you to first, one that says something along the lines of
"Xlist:
Ylist:
FreqList:
Store RegEQ:
Calculate"
however it appears that mine just skips this step, setting Xlist as L1 and Ylist as L2.
I have looked around on my calculator for a while and haven't been able to find anything.
Stat Diagnostics is set to on.
If anyone can help me on this I would be greatly appreciative.
Can you use two different scales on a single set of axes?
Definitely! In fact, it's way more common for the scales to differ than be equal. For instance, the equation y=x^2 is curved (a parabola in fact). Well, there's nothing stopping you from scaling the y axis down by its square root, assuming you clearly label it that way, so that the graph is linear.
