A line with the equation [ y = 2x plus or minus anything ] is parallel to [ y = 2x - 4 ]. In general this is of the form y=mx+b where m is the slope and b the intercept. If the sign of the slope is changed and it's replaced with its reciprocal, 2x becomes -x/2, the line is perpendicular to the original line. Thus y=2x-4 is perpendicular to y=-x/2 - 4.

What is the difference between an expression and an equation is that an has an equal sign?
I think you mean this as an answer, not a question. An expression does not have an equals sign (e.g 2x4). An equation does have an equals sign (e.g 2x4=8).
What is Twice N equals 8?
if you mean 2n=8, then N=4, which translate to 2x4=8
Can you add a 2x4 by a 2x4 matrix?
Yes.
Why is 0.8 divided by 4 is 0.2?
because think of 2x4=8 and 8 divided by 4 or 2 equals 4 or2 OK :)
Write an equation of the line that passes through the point 4 comma 1 and has a slope of 2?
The general equation for a straight line is: y=mx+cm being the gradient (slope), and c being the y intercept (which isn't important in this question)So firstly, we substitute the slope into the rule which gives us:y=2x+cThen we substitute in the point (4,1), 4 being the x-value and 1 being the y-value. This means that when x=4, y=1, so if we put this into our equation:(4,1) => 1=2x4+c1=8+cNow subtract 8 from both sides-7 = cFinally, substitute your m and c into the rule and you get your straight line equation:y=2x-7

Is 2x4 equals 7 a statement?
2x4 does not equal 7, it equals 8. 2x4=8 is a correct statement.
What is 2x4 plus 1232 plus 0-2x4-1232 equals?
the answer is 0!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I was the one who made it an unanwser question?
What does -3 -2x4 equals?
The rule in /mathemtics, when no brackets are given, is DO THE MULTIPLCATUION/DIVISION before addition /subtraction. You calculator is programmed this way. Hence -3 -2 X 4 = -3 - 8 = -11 Notice I have made the mukltiplication be forde the subtraction. However, if the sum is wrtitten as (-3-2)x 4 , then you do the brackets first . ( -5) x 4 = -20 It is definitely NOT -6 x 4
