What is the slope and yintercept of y plus 4x plus 3?
There is no slope nor intercept because there is no equation, simply an expression.
How do you find the slope and y-intercept of an equation?
first of all, i dont see how slope and yintercept has anything to do with shopping. usually in an equation, y= mx+b, m stands for slope, and b is the y-intercept. x and y are just x and y. If the equation is mixed up, and is not in y=mx+b format, you need to solve to get y on one side, the slope, x, and whatever the presented constant is (which is the y-intercept) on the other side. hope this helps.
How do you verify the identity sinx cscx 1?
sinx cscx = 1 is the same thing as sinx(1/sinx) = 1 which is the same as sinx/sinx = 1. This evaluates to 1=1, which is true.
Parenthesis 1 plus tanx end parenthesis divided by sinx equals cscx plus secx?
(1 + tanx)/sinxMultiply by sinx/sinxsinx + tanxsinxDivide by sin2x (1/sin2x) = cscxcscx + tan(x)csc(x)tanx = sinx/cosx and cscx = 1/sinxcscx + (sinx/cosx)(1/sinx)sinx cancels outcscx + 1/cosx1/cosx = secxcscx + secx
Solve my homework problemIt's about using slope intercept form One problem is 2y equals 8x-2?
I shall do this one , but you must do the rest otherwise you will not learn. 2y = 8x - 2 is the given eq'n/ The straight line form is y = mx + c'. 'm' is the slope/gradient of the line 'c' is the y-intercept. So divide both sides by '2' ; this will result in 'y = ' Hence y = (8/2)x - 2/2 y = 4x - 1 is the straight line form of y = mx + c. So the slope is m = 4 The y-intercept is c = -1 NB for all linear equations this is the method. NNB Linear eq'n may appear in various forms. 2y = 8x - 2 2y - 8x = -2 2y - 8x + 2 = 0 y - 4x + 1 = 0 etc., So you need to algebraically rearrange into the y = mx + c form However, if there are powers of 'x' or 'y' it is NOT a straight line. Hope that helps!!!!
