∙ 10y agoIn y = 2x - 6, this is a function, and the value of y varies linearly with x.
So, the number of values here is infinite, since there are an infinite number of values that can be given for x. More detail is needed.

What is the maximum value of y equals -x2-x plus 6?
8
Vertex of graph x2-6x plus 5?
y=aX2+bX+c ---> y=X2-6X+5vertex formula is -b/2a( b=-6,a=1)vertex=-(-6)/2*1=6/2=3 y=32-6(3)+5---->y=-4so vertex is (3,4)
How do you solve a slope problem?
Use the slope formula (y2-y1)/(x2-x1) and yes x2 is the x-value of your second x coordinate. Meanwhile y2 is the second y coordinate.
What is the value of x2-3x-1 when x is -2 and y is 4?
It is 9, and the value of y is totally irrelevant.
What is the formula for the difference of two perfect squares?
that's x2 - y2 = (x-y)(x+y)

What are the points of intersection of the curves y equals x2 -7x plus 8 and y equals -x2 plus 9x -6 showing work?
If: y = x2-7x+8 and y = -x2+9x-6 Then: x2-7x+8 = -x2+9x-6 So: 2x2-16x+14 = 0 => x2-8x+7 = 0 Therefore: x = 1 and x = 7 By substitution: x =1, y = 2 and x = 7, y = 8 Points of intersection: (1, 2) and (7, 8)
What is the formula for the difference of two perfect squares?
that's x2 - y2 = (x-y)(x+y)
What are the solutions for y equals x squared and y equals x plus 6?
if: y = x2 y = x + 6 then x2 = x + 6 => x2 - x - 6 =0 => (x - 3)(x + 2) = 0 => x = 3 or -2 => y = 9 or 4 respectively, ie the points (3, 9) and (-2, 4).
What is the slope of a line that goes through the points 2 5 and 8 6?
(Y2-Y1)/(X2-X1) Where Y2= second Y value (6) Y1= first Y value (5) same for X values (6-5)/(8-2)=1/6
What is the formula of square of binomial?
(x + y)2 = x2 + 2xy + y2
What is the formula for calculating gradient?
change in Y divided by change in X. X is your field value(kilometers, miles, feet, etc) and Y is the units of your isolines(degrees, feet, meters, etc) Y2-Y1 / X2-X1 = Y2-Y1 DIVIDED BY X2-X1
Solution set of y equals x2 - x - 6?
